  Dynamics, Aerosol, Cloud and Precipitation Observations in the Pristine Environment of the Southern Ocean (DACAPO-PESO), Descrição: The project DACAPO-PESO is motivated by need to provide an explanation for the observed evidence of strong regional contrasts in heterogeneous ice formation efficiency. Various studies report that heterogeneous ice formation in the temperature range between -40 and 0°C is more efficient in the northern hemisphere than in the southern hemisphere. This conclusion was also supported by lidar observations of stratiform clouds in the northern midlatitudes (Leipzig, Germany, 51°C) and the southern midlatitudes (Punta Arenas, Chile, 53.1° S) which were conducted by Leibniz Institute for Tropospheric Research (TROPOS), Leipzig, Germany. Meanwhile, the mobile ground-based supersite LACROS of TROPOS is operated to provide observations with co-located lidar, cloud radar, precipitation-profiling radar, Doppler lidar, microwave radiometer, sun photometer, precipitation disdrometer, a radiation balance station, an all-sky cloud camera and irregular launches of radiosondes. These observations allow to derive aerosol-cloud-dynamics-precipitation interaction in much higher detail than with lidar alone. In Europe LACROS has collected multi-year datasets of these observations for the continental site of Leipzig and the strongly mineral-dust-burden subtropical region of Cyprus. In a next step, LACROS will be deployed in Punta Arenas, Chile, which is the southernmost point of continental land mass of the southern hemisphere showing a mitlatidudinal to subpolar climate. Contrasting the LACROS observations from Leipzig, Cyprus, and Punta Arenas, which are based on the same instrumentation, will allow to infer the reasons for the regional observed differences in heterogeneous ice formation efficiency.. , Situação: Em andamento; Natureza: Pesquisa. , Alunos envolvidos: Mestrado acadêmico: (2) Doutorado: (2) . , Integrantes: Boris Barja González - Integrante / SEIFERT, PATRIC - Integrante / Albert Ansmann - Coordenador / Johannes Bühl - Integrante / Martin Radenz - Integrante / Teresa Vogl - Integrante / Heike Kalesse - Integrante / Willi Schimmel - Integrante.Financiador(es): Leibniz-Institut für Troposphärenforschung - Auxílio financeiro.

  The Future of Climate Extremes in the Caribbean (XCUBE), Descrição: The North Atlantic basin, including the Caribbean Sea and the Gulf of Mexico, exhibits substantial interannual to interdecadal variability of tropical cyclone activity. Major hurricanes are the most extreme type of Atlantic cyclones, and have major impacts on humans and society in the surrounding regions. Increases in key measures of Atlantic hurricane activity over recent decades are believed to reflect to a large degree increases in tropical Atlantic warming (e.g., Emmanuel, 2005). During recent decades a lot of attention has been paid to the apparent observed multidecadal pattern in Atlantic sea surface temperature (SST), often referred to as Atlantic Multidecadal Variability (AMV). The oceans are the primary energy source for tropical cyclones, so understanding long-term changes in Atlantic SSTs could therefore potentially be of prime importance for understanding long-term hurricane variability. Some recent studies (e.g., Goldenberg et al. 2001; Zang and Delworth 2006) have in fact attributed recent increases in hurricane activity to natural climate variations associated to AMV, while others suggest that human-induced climate change are more important (Emmanuel 2005; Webster et al 2005). However, resolving this issue will require a much improved understanding of the governing mechanisms for long-term changes in Atlantic SSTs that are still missing. To what extent the AMO is driven by internal variations in the large-scale ocean circulation (Delworth and Mann 2000; Knight et al. 2005; Jungclaus et al. 2006) or external climate forcings such as volcanoes (e.g., Otterå et al. 2010) or anthropogenic factors (e.g., Mann and Emmanuel 2006) is still largely uncertain. Atlantic SST has further been linked to long-term variations in both Sahel and North Brazilian rainfall (e.g., Knight et al. 2006) as well as Indian monsoon changes (Luo et al. 2011). A better understanding of long-term (multidecadal) variations in Atlantic SSTs are therefore urgently needed. The XCUBE project?s goals are to better understand future changes in the Caribbean climate, with a special focus on hurricanes and drought; to provide training to researchers at INSMET, the Meteorological Institute in Cuba; and to improve the infrastructure at INSMET. , Situação: Concluído; Natureza: Pesquisa. , Alunos envolvidos: Graduação: (1) / Especialização: (1) / Mestrado acadêmico: (2) . , Integrantes: Boris Barja González - Integrante / René Estevan - Integrante / Juan Carlos Antuña Jr. - Integrante / Jorge Rosas - Integrante / ANTUÑA, JUAN CARLOS - Integrante / Frank Garcia - Integrante / Allan Robock - Integrante / Dr. Odd Helge Otterå - Coordenador / Dr. Maritza Ballester - Integrante / Nelson Diaz - Integrante / Michel Mesquita - Integrante.

  Cloud optical properties in the Amazon derived from ground and satellite based instruments, Descrição: This research proposal focuses on the determination of cirrus cloud optical properties in the Amazon region from different ground and satellite based instruments before and during GoAmazon/CHUVA Experiments. Understanding the behavior of the optical characteristics of clouds and their lifecycle will allow us to evaluate their interaction with solar and terrestrial radiation. A second objective of this proposal will be the evaluation of the cloud radiative effects. Cloud optical depths (COD) will be evaluated from the LIDAR and radiometer instruments, both installed in experimental sites upwind and downwind from Manaus city. Results will be compared with those obtained from satellite instruments. An evaluation of the cloud radiative forcing on the solar radiation will also be obtained by two different methods in the different sites of measurements: modeling and direct solar radiation measurements. These activities will be involved directly with the Green Ocean Amazon (GoAmazon) 2014/2015 experiment from ARM. This research on optical and radiative properties of cirrus clouds should allow, in the future, improving the representation of clouds in the atmospheric models, what is direct related to FAPESP Thematic project ?CHUVA - Cloud processes of tHe main precipitation systems in Brazil: A contribUtion to cloud resolVing modeling and to the GPM (GlobAl Precipitation Measurement)?.

  Recuperación de la Base de Datos de Radiación Solar de la Estación Camaguey., Descrição: La estación meteorológica de Camagüey cuenta con más de 30 años de observaciones actinométricas. Estas observaciones se hayan en papel y han sido procesadas manualmente. Existen algunas bases de datos de los resultados de estas observaciones, pero ninguna parte de la base de datos original y/o cubre todo el periodo de observaciones disponible. Además las Tablas KM-12 y TM- 12 que contienen la observación original y los resultados del procesamiento manual, respectivamente, ya muestran alarmantes signos de deterioro. El presente proyecto está destinado a recuperar la base de datos de mediciones actinométricas, creándola en soporte computacional y someterla a procesamiento y control de la calidad automatizado. Con este fin se recuperó una PC-386 dada de baja por rotura y se utilizará además una de las microcomputadoras de la Estación Lidar. La base de datos que se producirá cumplirá con los estándares internacionales para este tipo de información. Para este fin se combinara la experticidad y experiencia del personal de la Red de Estaciones y de la Estación Lidar. La ejecución de este proyecto permitirá ganar experiencia para acometer en un futuro la recuperación del archivo de datos del Centro Meteorológico Provincial (CMC). Como objetivo general del proyecto se persigue la creación de una base de datos computarizada de radiación solar que cumpla con los estándares internacionales. Crear una base de datos de observaciones actinométricas. Establecer la adición regular a dicha B/D de las nuevas observaciones que realicen. Elaborar y poner en explotación un software de cálculo de la radiación solar y control de la calidad de las observaciones. Adquirir experiencia en la recuperación de datos meteorológicos que permita acometer el rescate del archivo del CMC.. , Situação: Concluído; Natureza: Pesquisa. , Alunos envolvidos: Especialização: (1) / Mestrado acadêmico: (1) Doutorado: (1) . , Integrantes: Boris Barja González - Integrante / René Estevan - Integrante / Teresita Hernández - Integrante / Carlos Hernández - Integrante / Aramís Fonte - Integrante / Antuña, J.

  Caracterización de las Nubes Cirros sobre Camagüey, Descrição: This Project was related to climatology of the presence of cirrus clouds over the region of Camagüey in Cuba, which has been constructed from the analysis of three-hourly reports contained in the observations of six ground meteorological stations. The data was taken from 1971 to 2002; only in one station the data starts from 1976. The cirrus clouds occurrence values have been found higher in the named rainy period, there are values between 0.50 and 0.70. The diurnal cycle in the occurrence of cirrus clouds wasn?t analyzed, due there are a difficulty of the treatment of the night observations linked with the visibility reduction and the scarce of night observations. Also an analysis of the cirrus clouds subtypes reported was made. A subtype of cirrus clouds (cirrus spissatus) is the most predominant in all period at the half of time when the cirrus clouds are present, with frequency of occurrence values between 0.57 y 0.61. In the present project also the atmospheric extinction profiles from the SAGE II sensor onboard the Earth Radiation Budget Satellite (ERBS) have been used to analize the occurrence frequency and the optical and geometrical depth of the optically thin cirrus clouds over the Wider Caribbean region. The extinction ratio between the two wavelengths at 0.525 and 1.02 μm was used to separate the profiles containing only aerosols from thus containing a cloud/aerosols mixture (Kent and McCormick, 1991). This ratio shows a different behavior in the interaction between solar radiation crystal ice and aerosols at both wavelengths. The SAGE II dataset version 6.2 was used, extending 21 years, from October 1984 to August 2005. The results show a seasonal behavior in the cirrus clouds occurrence frequency; with a maximum of 35.5 and 17.2% in the rainy and little rainy periods, respectively. These peaks of cirrus clouds frequencies are located at 14.5 and 12.0 km of altitude. An occurrence of 9% was obtained above the tropopause level. About 75% of the. , Situação: Concluído; Natureza: Pesquisa. , Alunos envolvidos: Mestrado acadêmico: (1) Doutorado: (1) . , Integrantes: Boris Barja González - Coordenador / René Estevan - Integrante / Antuña, J.

  Characterization of the stratospheric and upper tropospheric aerosols over Central and Sud-America, Descrição: The present proposal addresses issues as determination of the spatio-temporal features of the lower stratospheric and upper tropospheric aerosols over Central and South America. Both satellite and lidar data will be used to achieve this goal. Two main periods will be subject of the study: the one with no volcanic perturbation (stratosphere aerosol background condition) and the post-volcanic periods. Particular attention will be dedicated to determine the temporal evolution of the aerosol extinction 3-D characteristics. It will be used for a preliminary evaluation of the STE considering the aerosols as tracers for the cross tropopause transport. Trajectory analysis will also be also to determine the geographic location of the potential aerosol sources as well as to complement the transport analysis aforementioned. Satellite data will consist of the SAGE II instrument dataset, the longest available global record of vertical aerosol profiles at various wavelengths. Aerosol backscattering profiles from the lidar stations located at Sao Jose dos Campos (Brazil) and Camagüey (Cuba) will be used as complimentary information. The upgrade of the current capabilities of the Camagüey lidar station is proposed, to maintain the ongoing middle atmosphere aerosol measurements. The present and future dataset resulting from the measurements made by this lidar project have played and will be playing an important role in current and future international research projects. We also plan to conduct the workshop "Lidar measurements in the Americas". It will promote the initial agreements as well as coordinate the joint effort necessary for the future establishment of a lidar network in the Americas. Such network will be based on the existing lidar projects, promoting its development through cooperation and interchange. Such a network will also help increase the number of LIDAR systems operating in the region.. , Situação: Concluído; Natureza: Pesquisa. , Alunos envolvidos: Doutorado: (1) . , Integrantes: Boris Barja González - Integrante / Mario Lavorato - Integrante / Pablo Canziani - Integrante / René Estevan - Integrante / Antuña, J.
