ENVEO - EUMETSAT Projects

EUMETSAT SEDOS-2 - Snow Cover / Extent Demonstrator from Optical Sensors – Follow on Activities (2024 - 2025)

The project develops a method and system for generating snow cover products from the Meteosat Third Generation (MTG) Flexible Combined Imager (FCI), exploiting the high temporal observation capabilities of geostationary optical sensors.

EUMETSAT SEDOS - Snow Cover / Extent Demonstrator from Optical Sensors (July 2019 - July 2021)

The area extent of the seasonal snow cover is a key parameter for a wide range of applications in meteorology, climate monitoring, global change research, hydrology, water management and ecology. This study develops and implements a prototype processing system for generation of snow extent products from EPS METIMAGE. The prototype system is demonstrated and evaluated using data of the optical sensors of Sentinel-3 featuring similar spectral imaging bands as METimage.

The primary objectives of this study are

Develop, implement and validate an algorithm and prototype system to prepare for the generation of snow extent products from METimage which will be flown on EPS-SG, and FCI onboard of MTG.
Demonstrate and evaluate the developed methods and prototype system using data of the optical sensors SLSTR and OLCI onboard of Sentinel-3 featuring similar spectral imaging bands as METimage. This task will include the generation and validation of a 1-year time series of daily snow cover products over Europe.
Demonstrate the operational capabilities of the prototype system by generating a time series of Pan-European snow products from Sentinel-3 data in Near Real time.

EUMETSAT OSMON - An automatic tool for assessing and anaylsing the geolocation accuracy of medium resolution optical sensors (November 2018 - November 2020)

OSMON develops, implements and demonstrates the use of a platform independent modular software tool for assessing and monitoring the geolocation accurary of medium resolution optical sensors, expanding on proven technology and providing robust algorithms. The tool supports Level-1 products from current medium resolution EUMETSAT sensors (such as AVHRR, SLSTR, OLCI) and should be easily extendable to near-future sensors like MetImage, etc.

The main project objectives are

Generating and delivering a stand-alone environment for assessing the geolocation accuracy of moderate to high resolution optical satellite sensors.
Developing, testing and documenting an automatic monitoring and reporting system for detecting and quantifying possible geolocation errors.
Providing tools for continuously monitoring geolocation performance of image data as they are acquired and circulated to users.
Enabling quick and reliable validation of new datasets in case of a change in the processing baseline for optical sensor products that might affect the geolocation accuracy.
Evaluating the spectral and temporal registration accuracy and stability of EUMETSAT optical sensor payloads by analysing long time series.
