Event - Training
Advanced Training Course on Ocean Remote Sensing 2006
The objective of the course was to provide first-hand information on a broad range of ocean research topics including key principles of SAR, Radar Altimetry, Ocean Colour and Sea Surface Temperature measurements, processing algorithms, data products and their use in oceanographic applications.
Mission - Earth Explorers
Aeolus
The Aeolus mission which was launched into space on 22 August 2018 and was retired on 30 April 2023, provided global observations of wind profiles from space to improve the quality of weather forecasts, and to advance our understanding of atmospheric dynamics and climate processes.
Tools - Processing
Aeolus VRE
The Aeolus Virtual Research Environment (VRE) is the latest extension to the VirES for Aeolus service, which offers more direct and in-depth data exploitation of the Aeolus mission. The VRE is a cloud service that provides a web-based development environment in the form of a JupyterLab workspace.

COVID-19: Aeolus and weather forecasts
The drop in commercial flights has led to fewer measurements for weather forecasts, but fortunately, ESA’s Aeolus satellite mission is helping to fill the gap.

Drones join the campaign to validate Aeolus data
In June and September 2022, the Askos component of the Joint Aeolus Tropical Atlantic Campaign (JATAC), organised by ESA and its international partners, was expanded with new ground-based, drone and radiosonde measurements. The main objective of this campaign was to calibrate and validate Aeolus satellite observations.

Dust aerosol campaign validates Aeolus data
Prepared, implemented and executed by a consortium of French universities and research institutions, under the umbrella of the French Space Agency (CNES) and the French National Centre for Scientific Research (CNRS), the Clouds-Atmospheric Dynamics–Dust Interactions in West Africa (CADDIWA) campaign took place on Sal Island in Cape Verde, from 6 to 25 September 2021.
Mission - Heritage Missions
Envisat
Envisat was ESA's successor to ERS. Envisat carried ten instruments aboard for a wide range of Earth observing fields. The mission was operational from 2002 to 2012.
Data - Fast Registration with immediate access (Open)
Envisat ASAR Wave Imagette Cross Spectra L1 [ASA_WVS_1P]
The ASAR Wave product is extracted from the combined SLC and Cross Spectra product, ASA_WVI_1P, which is generated from data collected when the instrument was in Wave Mode using the Cross Spectra methodology. The product is meant for Meteo users. The spatial coverage is up to 20 spectra acquired every 100 km, with a minimum coverage of 5km x 5km. The file size has a maximum of 0.2 Mbytes. Auxiliary data include Orbit state vector, Time correlation parameters, Wave Processing parameters ADS, Wave Geolocation ADS, SQ ADS. The product provides a continuation of the ERS-SAR wave mode data. Output: Wavelength range from 20 to 1000 m in 24 logarithmic steps.

Envisat ASAR WS Single Look Complex L1 [ASA_WSS_1P]
The Level-1B data product offered by ESA from the ASAR Wide-Swath Mode (WS) is a multi-look detected product, ASA_WSM_1P, intended to support applications that exploit intensity data. In order to support the development of new applications with the ASAR ScanSAR data, a WSM product providing phase information has been developed and implemented in the ESA ASAR processor - the Wide-Swath Single-Look complex product (ASA_WSS_1P). This product is mainly used for INSAR applications based either on wide-swath/wide-swath pairs or wide-swath/image mode pairs, applications of ocean current mapping, large-area ocean wave retrievals and atmospheric water vapour characterisation. It is important to mention that the standard ESA WSS product is based on the prototype WSS processor developed by Polimi/Poliba, which has also been used to generate prototype products for testing potential and preparing the exploitation of the WSS product. The ESA ASA_WSS_1P product is available as a standard Envisat ASAR product. The ASA_WSS_1P product format is slightly different from other ASAR products since: There are 5 different MDSs, one per sub-swath A "Doppler Grid" ADS has been included to support ocean current mapping applications There are 5 records in the MPP ADS, one per sub-swath There are 5 records in the SQ ADS, one per sub-swath. Other key characteristics of the ASA_WSS_1P product are summarised below: Processing is fully phase preserving Data in the MDSs is sampled in a common grid both in range and in azimuth Standard product is 60 sec long with 80 m az. pixel spacing Auxiliary timeline information has been added in the Main Processing Parameters ADS Elevation antenna pattern correction is applied by default (although the product is a single-look complex). Spatial Resolution: Approximately 8 m slant range x 80 m azimuth.
