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.

Landsat 8 Collection 2 European Coverage
This dataset contains the European coverage of Landsat-8 Collection 2 data, both Level-1 and Level-2, acquired since the beginning of the mission. Landsat-8 Collection 2 is the result of a reprocessing effort on the archive and on newly acquired products with significant improvement with respect to Collection 1 on data quality, obtained by means of advancements in data processing and algorithm development. Primarily, this involves a relevant improvement in the absolute geolocation accuracy (now re-baselined to the European Space Agency Copernicus Sentinel-2 Global Reference Image (GRI) but also includes updated digital elevation modelling sources, improved Radiometric Calibration (even correction for the TIRS striping effect), enhanced Quality Assessment Bands, updated and consistent metadata files and usage of Cloud Optimised Georeferenced (COG) Tagged Image File Format. Landsat-8 Level-1 products combine data from the two Landsat instruments, OLI and TIRS. The Level-1 products generated can be either L1TP or L1GT: L1TP - Level-1 Precision Terrain (Corrected) (L1T) products: Radiometrically calibrated and orthorectified using ground control points (GCPs) and digital elevation model (DEM) data to correct for relief displacement. The highest quality Level-1 products suitable for pixel-level time series analysis. GCPs used for L1TP correction are derived from the Global Land Survey 2000 (GLS2000) data set. L1GT - Level-1 Systematic Terrain (Corrected) (L1GT) products: L1GT data products consist of Level-0 product data with systematic radiometric, geometric and terrain corrections applied and resampled for registration to a cartographic projection, referenced to the WGS84, G873, or current version. The dissemination server contains three different classes of Level-1 products Real Time (RT): Newly acquired Landsat-8 OLI/TIRS data are processed upon downlink but use an initial TIRS line-of-sight model parameters; the data are made available in less than 12 hours (4-6 hours typically). Once the data have been reprocessed with the refined TIRS parameters, the products are transitioned to either Tier 1 or Tier 2 and removed from the Real-Time tier (in 14-16 days). Tier 1 (T1): Landsat scenes with the highest available data quality are placed into Tier 1 and are considered suitable for time-series analysis. Tier 1 includes Level-1 Precision and Terrain (L1TP) corrected data that have well-characterized radiometry and are inter-calibrated across the different Landsat instruments. The georegistration of Tier 1 scenes is consistent and within prescribed image-to-image tolerances of ≦ 12-metre radial root mean square error (RMSE). Tier 2 (T2): Landsat scenes not meeting Tier 1 criteria during processing are assigned to Tier 2. Tier 2 scenes adhere to the same radiometric standard as Tier 1 scenes, but do not meet the Tier 1 geometry specification due to less accurate orbital information (specific to older Landsat sensors), significant cloud cover, insufficient ground control, or other factors. This includes Systematic Terrain (L1GT) and Systematic (L1GS) processed data. Landsat-8 Level-2 products are generated from L1GT and L1TP Level-1 products that meet the <76 degrees Solar Zenith Angle constraint and include the required auxiliary data inputs to generate a scientifically viable product. The data are available a couple of days after the Level-1 T1/T2. The Level-2 products generated can be L2SP or L2SR: L2SP - Level-2 Science Products (L2SP) products: include Surface Reflectance (SR), Surface Temperature (ST), ST intermediate bands, an angle coefficients file, and Quality Assessment (QA) Bands. L2SR - Level-2 Surface Reflectance (L2SR) products: include Surface Reflectance (SR), an angle coefficients file, and Quality Assessment (QA) Bands; it is generated if ST could not be generated. Two different categories of Level-1 products are offered: LC with Optical, Thermal and Quality Map images, LO with Optical and Quality Map images (Thermal not available). For the Level-2 data, only LC combined products are generated.
