Efficient consumption of on-board hydrazine allows operating nominally Envisat until 2010. But most of hydrazine will be consumed by 2010. The Envisat 3-years extension requests a modification of the orbital parameters in 2010 to be able to operate the satellite with minimum hydrazine. EnvisatEnvisat satellitesatellite statusstatus andand evolutionevolution Responding to a strong demand coming from all user communities, ESA has elaborated a technical solution to extend the Envisat mission beyond 2010 based on the following criteria: 1. to keep the current nominal mission for as long as possible (i.e. until 2010), 2. to extend the mission well beyond 2010, 3. to ensure the continuity of the max. number of Envisat applications beyond 2010, 4. to follow the mitigation rules for space debris risk at end of mission. The solution, based on a relaxation of the inclination drift and on a decrease of the orbit altitude by 17.4 km will allow extending the mission lifetime by 3 years, i.e. until 2013. Æ the solution is compatible with the current Envisat applications, except SAR interferometry applications. The orbital change is currently planned for October 2010. The new orbit repeat cycle will be 30 days (current orbit cycle is 35 days).

  • The Use of Sentinel-3 Imagery to Monitor Cyanobacterial Blooms
    environments Article The Use of Sentinel-3 Imagery to Monitor Cyanobacterial Blooms Igor Ogashawara Department of Earth Sciences, Indiana University-Purdue University Indianapolis, Indianapolis, IN 46202, USA; [email protected] Received: 6 May 2019; Accepted: 1 June 2019; Published: 3 June 2019 Abstract: Cyanobacterial harmful algal blooms (CHABs) have been a concern for aquatic systems, especially those used for water supply and recreation. Thus, the monitoring of CHABs is essential for the establishment of water governance policies. Recently, remote sensing has been used as a tool to monitor CHABs worldwide. Remote monitoring of CHABs relies on the optical properties of pigments, especially the phycocyanin (PC) and chlorophyll-a (chl-a). The goal of this study is to evaluate the potential of recent launch the Ocean and Land Color Instrument (OLCI) on-board the Sentinel-3 satellite to identify PC and chl-a. To do this, OLCI images were collected over the Western part of Lake Erie (U.S.A.) during the summer of 2016, 2017, and 2018. When comparing the use of traditional remote sensing algorithms to estimate PC and chl-a, none was able to accurately estimate both pigments. However, when single and band ratios were used to estimate these pigments, stronger correlations were found. These results indicate that spectral band selection should be re-evaluated for the development of new algorithms for OLCI images. Overall, Sentinel 3/OLCI has the potential to be used to identify PC and chl-a. However, algorithm development is needed. Keywords: phycocyanin; chlorophyll-a; water quality; Lake Erie; cyanobacteria; bio-optical modeling 1.

  • Synthetic Aperture Radar in Europe: ERS, Envisat, and Beyond
    SYNTHETIC APERTURE RADAR IN EUROPE Synthetic Aperture Radar in Europe: ERS, Envisat, and Beyond Evert Attema, Yves-Louis Desnos, and Guy Duchossois Following the successful Seasat project in 1978, the European Space Agency used advanced microwave radar techniques on the European Remote Sensing satellites ERS-1 (1991) and ERS-2 (1995) to provide global and repetitive observations, irrespective of cloud or sunlight conditions, for the scientific study of the Earth’s environment. The ERS synthetic aperture radars (SARs) demonstrated for the first time the feasibility of a highly stable SAR instrument in orbit and the significance of a long-term, reliable mission. The ERS program has created opportunities for scientific discovery, has revolutionized many Earth science disciplines, and has initiated commercial applica- tions. Another European SAR, the Advanced SAR (ASAR), is expected to be launched on Envisat in late 2000, thus ensuring the continuation of SAR data provision in C band but with important new capabilities. To maximize the use of the data, a new data policy for ERS and Envisat has been adopted. In addition, a new Earth observation program, The Living Planet, will follow Envisat, offering opportunities for SAR science and applications well into the future.

Therefore, there is a strong need to validate the OLCI products to be sure that the technical capabilities provided will be used in the best possible way in water quality monitoring and research. The Baltic Sea is an optically complex waterbody where many ocean colour products, performing well in other waterbodies, fail. We tested the performance of standard Case-2 Regional/Coast Colour (C2RCC) processing chain in retrieving water reflectance, inherent optical properties (IOPs), and water quality parameters such as chlorophyll a, total suspended matter (TSM) and coloured dissolved organic matter (CDOM) in the Baltic Sea.
