  Distributed Rating curves along the Amazon Contributors gained by altiKa - DRACK, Descrição: The objective of the projet is to use the high resolution and high accuracy AltiKa altimetry over rivers to enable the dense computation of refined rating curves all over the Amazon basin. It is expected that the high accuracy rating curves so determined will help to improve the pre-Altika level values obtained with the Ku band altimetry operated in the ERS and ENVISAT missions. Subsequently, we expect to compute hundreds of >20 year-long uninterrupted heights series over tens of tributaries in the Amazon basin. At the end of the AltiKa mission, these series will be used to compute height and slope climatologies (monthly means) and finally, distributed discharge climatologies. , Situação: Em andamento; Natureza: Pesquisa. , Integrantes: Stéphane Calmant - Coordenador / Santos da Silva, Joecila - Integrante., Financiador(es): Centre Nationale d'Études Spatiales - Cooperação.

  From Ocean to Inland Water Altimetry Monitoring - FOAM, Descrição: Due to the increasing need of altimetry to monitor inland waters and in preparation to future missions (e.g., SARAL/AltiKa, Sentinel-3, Jason 3, Jason CS, SWOT) we propose to integrate the calibration activities on the oceanic domain and those on different water bodies such as rivers and lakes. CAL/VAL activities on the oceanic domain have a long history and protocols are well established. CAL/VAL activities on rivers and lakes are much recent but in turn they enable to avoid the contributions of the Sea Surface Bias (SSB) and liquid tides in the range calibration and to address other problems such as the performance of the various retracking algorithms, altimeter technologies (LRM/SAR), wavelength (Ku/Ka), and more globally assess the quality of the geophysical corrections. This projet will then pay a particular attention of the short wavelength signatures in the altimetry data since SARAL/AltiKa will be the first mission to distribute 40 Hz measurements on reduced footprints owing to the Ka band pulse. The proposed CAL/VAL activities are thus focused not only on the important continuity between past, present and future missions but also on the reliability between offshore, coastal and inland altimetric measurement. Purpose is to aggregate the past effort of several groups, in order to notably establish a homogeneous network of calibration site geographically distributed for more robust characterization of the existing and future radar altimeter system instrument biases and their drifts. The main objectives of the FOAM project continuation is two-fold: (i) ensure the experiments already conducted during the first part of the FOAM project (2008-2012) and (ii) conduct new developments in terms of processing and technology (GNSS reflectometry (GNSS-R), GPS buoy design and processing). , Situação: Em andamento; Natureza: Pesquisa. , Integrantes: Stéphane Calmant - Integrante / Santos da Silva, Joecila - Integrante / P.

High accuracy time series will be established using all the past and present missions that are relevant for hydrology, e.g. ERS-2, ENVISAT, AltiKa, Cryosat and SENTINEL-3 on the one hand,TOPEX/POSEIDON, JASON-2 and 3 on the other hand. The VALS Tool will be used to process the altimetry data. In addition, the ability of such nadir altimetry to compute discharge variations and the limitations of the method, will also be examined in view of the improvements that the large swath altimetry and imagery provided by the SWOT should bring to the actual monitoring/alert system based on in situ measurements emplaced by the Brazilian Agencies in the Amazon basin. , Situação: Concluído; Natureza: Pesquisa. , Integrantes: Stéphane Calmant - Integrante / Santos da Silva, Joecila - Coordenador., Financiador(es): Centre Nationale d'Études Spatiales - Cooperação.

  Enlarged validation of the Alkika measurements and associated parameters ALTIKAMALA, Descrição: The groups joined in this project have all long term expertise in the calibration and/or validation of altimetry products. The French collaborators of the project already joined in a collective project for JASOn-2, FOAM. The objective of the project being to arrive at a global vision of the cal/val of a mission, the group has been enlarged in order to also enlarge the studied parameters and geographical spread of studied places. The cal/val will extend from the orbit analysis, the different ranges distributed in the GDRs in various contexts (open sea, coastal area, lakes, rivers, land), the meteo corrections and some parameters distributed in the GDRs such as the wave height. Also, this project will pay a particular attention of the short wavelength signatures in the altimetry data since AltiKa will be the first mission to distribute 40 Hz measurements on reduced footprints owing to the Ka band pulse. For this specific point, we propose to compare the short wavelengths structures evidenced in the AltiKa profiles with imagery at two places: Lake Issyk-kul and Amazon river stems. These two places have been selected because there, dense mapping of the water surface can be performed with GPS buoys. , Situação: Concluído; Natureza: Pesquisa. , Integrantes: Stéphane Calmant - Coordenador / Santos da Silva, Joecila - Integrante., Financiador(es): Centre Nationale d'Études Spatiales - Auxílio financeiro.

  Iniciativa de Hidrologia Espacial Amazônica - IHESA, Descrição: A possibilidade de se fazer o monitoramento de parâmetros ambientais de modo remoto, especialmente a partir dos anos 70, motivou um processo de re-leitura de muitas ciências, dentre as quais a hidrologia. A incorporação de métodos de sensoriamento remoto na sistemática observacional hidrológica permite hoje cunhar um novo termo que induz a uma nova disciplina: a Hidrologia Espacial. A hidrologia espacial tem ainda limitações de uso, mas seu desenvolvimento tem sido muito rápido em muitas regiões do globo, utilizadas como áreas teste. Uma dessas regiões muito visada pelas grandes dimensões de seus cursos d água é a Amazônia, na qual muitos estudos têm sido realizados. No entanto, as maiores iniciativas na região Amazônica têm sido externas à região (notadamente nos Estados Unidos e França). Assim é que a presente proposta pretende se associar a essas iniciativas internacionais e criar uma iniciativa baseada na própria região Amazônica, com a participação de diversas entidades nacionais, internacionais e da região interessadas em desenvolver o uso desta tecnologia. A Iniciativa de Hidrologia Espacial para a Amazônia (IHESA) quer ser uma rede de entidades (UFAM, UEA, INPA, IPH/UFRGS, IRD, ANA, SIPAM, Defesa Civil - AM e diversos colaboradores de países Amazônicos), que juntas pretendem estudar aplicações para as diferentes técnicas, de sensoriamento remoto, hoje disponíveis no tema água. Tal iniciativa se direciona no sentido de melhorar e complementar a atual sistemática de monitoramento hidrológico da Amazônia. IEHSA, quer também, permitir a elaboração de programas pilotos que possam ser utilizados por entidades governamentais (notadamente ANA, SIPAM e Defesa Civil) no monitoramento e na modelagem dos complexos processos hidrológicos existentes na Bacia Amazônica. , Situação: Em andamento; Natureza: Pesquisa. , Integrantes: Stéphane Calmant - Integrante / Marcelo Rollnic - Coordenador., Financiador(es): Financiadora de Estudos e Projetos - Auxílio financeiro.
