New cross-calibration readies PROBA-1 data for climate research

While PROBA-1 has already exceeded expectations by suppling over 21 years of Earth observation hyperspectral data, recent cross-calibration activities are aiming to ensure the data will robustly serve long time-series research, even when the satellite ends operations.

Release of CHRIS PROBA-1 toolbox for SNAP

PROBA -1 continues to provide valuable hyperspectral data to the scientific community, and so the tools to handle this data have been incorporated into ESA’s SNAP multi-mission toolbox.

Data - EO Sign In Authentication (Open)

PROBA-1 HRC

The HRC Level 1A product is an image with a pixel resolution of 8m. The data are grey scale images, an image contains 1026 x 1026 pixels and covers an area of 25 km2. HRC data is supplied in BMP format. All PROBA-1 passes are systematically acquired according to the current acquisition plan, HRC data are processed every day to Level 1A and made available to ESA users. Spatial coverage: Check the spatial coverage of the collection on a map available on the Third Party Missions Dissemination Service.

Comparing Three Canopy Reflectance Models with Hyperspectral Multi-Angular Satellite Data

Studies that compare modelled reflectances with satellite-measured reflectances for different wavelengths and view angles are still rare. We compared model outputs from three different canopy reflectance models (SLC, FRT and INFORM) with satellite measured reflectances (Chris/PROBA).
