ERS ATSR fourth Reprocessing datasets available to users
The fourth Reprocessing of the ATSR L1B datasets derived from the ERS-1 and ERS-2 satellites have now been released to users by the European Space Agency (ESA).
ERS ATSR L1B Brightness Temperature/Radiance [ER1_AT_1_RBT / ER2_AT_1_RBT]
Band measurements with associated uncertainty estimates. The ERS-1/2 ATSR Level 1B Brightness Temperature/Radiance products (RBT) contain top of atmosphere (TOA) brightness temperature (BT) values for the infra-red channels and radiance values for the visible channels, when available, on a 1-km pixel grid. The visible channels are only available for the ATSR-2 instrument. Values for each channel and for the nadir and oblique views occupy separate NetCDF files within the Sentinel-SAFE format, along with associated uncertainty estimates. Additional files contain cloud flags, land and water masks, and confidence flags for each image pixel, as well as instrument and ancillary meteorological information. The ATSR-1 and ATSR-2 products [ER1_AT_1_RBT and ER2_AT_1_RBT], in NetCDF format stemming from the 4th ATSR reprocessing, are precursors of Envisat AATSR and Sentinel-3 SLSTR data. They have replaced the former L1B products [AT1_TOA_1P and AT2_TOA_1P] in Envisat format from the 3rd reprocessing. Users with Envisat-format products are recommended to move to the new Sentinel-SAFE like/NetCDF format products, and consult the ERS ATSR Product Notice Readme document. The processing updates that have been put in place and the expected scientific improvements for the ERS ATSR 4th reprocessing data have been outlined in full in the User Documentation for (A)ATSR 4th Reprocessing Products
New campaign dataset supports validation of upcoming FORUM mission
A new dataset has been released for the FINESSE at Andøya campaign, which took place in Norway in 2023.
FINESSE at Andøya 2023
The Andøya campaign was undertaken in support of the Earth Explorer 9 Far-infrared Outgoing Radiation Understanding and Monitoring (FORUM) mission.

ESA's multi-level global thermosphere data products consistent with Swarm and GRACE (-FO)
In this project, the possibility of using the space-based along-track Thermospheric Neutral Density (TND) estimates for generating the European Space Agency (ESA)'s Level 3 (L3) global multi-level TND data products is assessed.
Swarm Ionospheric Polar Electrodynamics
The goal of the Swarm ionospheric polar electrodynamics (SWIPE) project is to create and disseminate the most advanced models of high-latitude Joule dissipation, ionospheric convection, and ionospheric conductances.
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.
Swarm Ion Temperature Estimation
The main objective of Swarm Ion Temperature Estimation (SITE) project is to estimate ion temperatures along the orbits of Swarm satellites using available LP electron density and temperature measurements, and numerical models.
Plasmapause Related boundaries in the topside Ionosphere as derived from Swarm Measurements
In the project, Plasmapause Related boundaries in the topside Ionosphere as determined from Swarm Measurements (PRISM), the team develop products that characterise position of the plasmapause related phenomena in the topside ionosphere.
Space data help to unravel the complexities of Earth’s atmosphere
As the impacts of the climate crisis intensify, scientists are using ESA’s Earth observation archives to investigate atmospheric processes and their influences on the planet’s changing environment.
Exploring the prevailing achievements and future directions of Aeolus
A tight-knit community of European remote sensing experts converged on the Italian island of Sicily last month to discuss how the strong success of ESA’s Aeolus mission is shaping scientists’ understanding of the winds that sweep across the planet.
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.
Launch of Aeolus VRE
The Aeolus Virtual Research Environment (VRE) is a cloud service, which provides users with a web-based development environment in the form of a JupyterLab workspace.
How Envisat helped to shape global understanding of Earth’s systems
Twenty years have passed since a ground-breaking European spacecraft designed to deliver unprecedented insight into the planet’s changing environment was lofted into orbit.
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.
Odin OSIRIS data products
The Odin OSIRIS (Optical Spectrograph and Infra-Red Imaging System) data provides vertical profiles measures of spectrally dispersed, limb scattered sunlight from the upper troposphere into the lower mesosphere. The data products are regularly processed and provide Ozone density vertical profiles (both Level 2 and Level 3), vertical profiles of stratospheric Aerosol (both Level 2 and Level 3), slant column densities of nitrogen dioxide NO2 profiles (Level 2), stratospheric BrO profiles (Level 2).
VERA
VERtical coupling in Earth's Atmosphere at mid and high latitudes (VERA) is a project in response to the ESA ITT "Swarm+ Coupling: High-Low Atmosphere Interactions" with the duration of 16 months.
Swarm Outflow
The Swarm+ Coupling High-Low Atmosphere Interactions: Ion Outflow ("Swarm+ Outflow") project, which began in May 2019, centres on using Swarm spacecraft to tackle unanswered questions around non-thermal processes that lead to ion outflow.
