    ESA's improved Earth system data records: what is in store for the future?

    Fundamental Data Records (FDRs) are instrumental in advancing our understanding of Earth systems and for addressing societal challenges effectively. These long-term records contain uncertainty-quantified, calibrated and geo-located multi-instrument/multi-platform satellite sensor data spanning several decades to support climate-related applications.

    AVHRR Level-1B Local Area Coverage Imagery

    This collection is composed of AVHRR L1B products (1.1 km) reprocessed from the NOAA POES and Metop AVHRR sensors data acquired at the University of Dundee and University of Bern ground stations and from the ESA and University of Bern data historical archive. The product format is the NOAA AVHRR Level 1B that combines the AVHRR data from the HRPT stream with ancillary information like Earth location and calibration data which can be applied by the user. Other appended parameters are time codes, quality indicators, solar and satellite angles and telemetry. Two data collections cover Europe and the neighbouring regions in the period of 1 January 1981 to 31 December 2020 and the acquired data in the context of the 1-KM project in the ‘90s. During the early 1990’s various groups, including the International Geosphere-Biosphere Programme (IGBP), the Commission of the European Communities (CEC), the Moderate Resolution Imaging Spectrometer (MODIS) Science Team and ESA concluded that a global land 1 KM AVHRR data set would have been crucial to study and develop algorithms for several land products for the Earth Observing System. USGS, NOAA, ESA and other non-U.S. AVHRR receiving stations endorsed the initiative to collect a global land 1-km multi-temporal AVHRR data set over all land surfaces using NOAA's TIROS "afternoon" polar-orbiting satellite. On 1 April 1992, the project officially began up to the end of 1999 with the utilisation of 23 stations worldwide plus the NOAA local area coverage (LAC) on-board recorders. The global land 1-km AVHRR dataset is composed of 5 channels, raw AVHRR dataset at 1.1 km resolution from the NOAA-11 and NOAA-14 satellites covering land surfaces, inland water and coastal areas. Global Land 1 km AVHRR Data Set Project HRPT Ground Station Network (as of 1 April 1992) and Acquisition Areas for LAC Recorded Data Spatial coverage: Check the spatial coverage of the collection on a map available on the Third Party Missions Dissemination Service: AVHRR L1B 1.1 KM AVHRR L1B LAC Out-of-Europe.

    PROBA-1 CHRIS Level 1A

    CHRIS acquired a set of up to five images of each target during each acquisition sequence, these images were acquired when PROBA-1 was pointing at distinct angles with respect to the target. CHRIS Level 1A products (supplied in HDF data files, version 4.1r3) include five formal CHRIS imaging modes, classified as modes 1 to 5: Mode Name Swath Spectral Bands/Ground Resolution Mode 1 Aerosols 13 km 62 at 34 m (773 nm / 1036 nm) Mode 2 Water bands 13 km 18 at 18 m Mode 3 Land channels 13 km 18 at 18 m Mode 4 Chlorophyll band set 13 km 18 at 18 m Mode 5 Land channels 6.5 km 37 at 18 m Spatial coverage: Check the spatial coverage of the collection on a map available on the Third Party Missions Dissemination Service.
