Φ-Week Triumphs
In its fourth edition, Φ-Week presented the scientific community with amazing opportunities and projects—thus running alongside innovation at 360 degrees.
Xinjiang Uygur Region (China), 2001
View the satellite image captured by ERS-2, highlighting the northernmost region between Kazakhstan and Mongolia.
wind-scatterometer-processing-requirements-from-sigma-nought-triplets-to-dealiased-wind.pdf
This document defines the ground processing algorithms for the ERS-1 AMI wind mode (Scatterometer) from the sigma nought triplets to the wind speed and direction, including the wind retrieval and the ambiguity removal processing.
Why the (A)SAR product name you see in OTF is not what you get?
The (A)SAR product names in the ESA (A)SAR On-The-Fly (OTF) catalogue differ slightly from the actual downloaded files due to the systematic addition of 1.5 seconds' margins before and after the requested scene.
What quality issues apply to the (A)SAR and ALOS PALSAR data?
Information on quality issues related to (A)SAR data, including specific disclaimers for Envisat ASAR and ALOS PALSAR products.
What is the format for ERS and Envisat (A)SAR data available via OTF?
Learn about the format for ERS SAR and Envisat ASAR data available via On-The-Fly (OTF).
What is the ESA online On-The-Fly dissemination service?
Explore ESA's On-The-Fly dissemination service (L-OADS), featuring Third Party Missions and ESAR products enabling immediate downloads upon request with a valid EO Sign-In account.
What are the Terms of Applicability?
Essential information about data ordering, accessibility conditions, and distribution constraints for TPM EO data.
Wetlands monitoring by ERS SAR data.pdf
The objectives of this study were to assess the suitability of ERS SAR images in monitoring the seasonal changes of the wetland areas which are difficult to monitor on land. Lake Bangweulu in Zambia was selected for the study. An additional objective was to carry out a comparison of the results obtained from both ERS SAR and NOAA AVHRR data.

VHR Data Quality in the limelight
In recent years, the satellite landscape has steadily expanded with a variety of very high resolution (VHR) commercial satellites, also emerging from new space providers. A result of this growth is an increased need to address data quality assurance.
VH-RODA and CEOS SAR workshop
The workshop provided an open forum for the presentation and discussion of current status and future developments related to the calibration and validation of space borne very high-resolution SAR and optical sensors and data products.
VH-RODA 2021 Workshop
The Very High-resolution Radar & Optical Data Assessment (VH-RODA) 2021 workshop was held online from 20–23 April 2021.
Very High Resolution data to take centre stage
In the last few years, European New Space providers have helped strengthen the offering of very high resolution remote sensing data products—a designated workshop this November aims to focus on the latest developments in this arena.
Venice (Italy), 2004
See the SAR multitemporal colour composite image of Venice.
Valencia (Spain), 2010
See Valencia in a SAR multitemporal composite image, created by merging three satellite images from 1995, 2003 and 2010.
UWA Processing Algorithm Specification
This technical note specifies version 2 of the algorithm to derive SAR wave spectrum products from ERS AMI wave mode data.
