    ERS-1/2 ATSR Averaged Surface Temperature [AT1/AT2_AR__2P]

    The Averaged Surface Temperature Product (AST) contains averaged geophysical data at two different resolutions, and with respect to two different averaging schemes: measurement data sets at resolutions of 0.5 by 0.5 degrees and 10 by 10 arcmin with respect to a latitude/longitude grid; other data sets contain data averaged over equal area cells of 50 by 50 km and 17 by 17 km aligned with the satellite ground track. Both top-of-atmosphere and surface data sets are provided. The surface temperature data sets provide, for sea cells, nadir and dual view sea surface temperatures, and for land cells, land surface temperature (currently 11 micron BT) and NDVI. Cloud data is also included. No ADS are included in the AST product; auxiliary data is contained within the MDS. The data sets of the AST product are arranged by surface type and resolution. The 3rd reprocessing of ATSR data was performed in 2013; the processing updates that have been put in place and the scientific improvements are outlined in full in the User Summary Note for the Third ERS ATSR Reprocessing.

    WS Quality Control Reports

    Quality Control Reports Products Availability The ERS Scatterometer mission has been reprocessed with the Advanced Scatterometer Processing System (ASPS) facility, providing data with improved radiometric quality and spatial resolution. ERS-2 AMI Wind Scatterometer data set has been reprocessed covering the period from 30 December 1996 to 5 July 2011 (end of mission). Read More Cyclic Reports The cyclic reports include a summary of the daily quality control made within the IDEAS (Instrument Data quality Evaluation and Analysis Service) and various sections describing the results of the investigations related to the Scatterometer. In each section, results are shown from the beginning of the mission in order to see the evolution and to outline possible "seasonal" effects. An explanation for the major events which have impacted the performance since launch is given, and comments about the events which occurred during the cycle are included. Read More ERS-2 Yaw Error Angle Monitoring - Weekly Reportsy The full set of results of the yaw processing is stored in an internal ESA product named HEY (Helpful ESA Yaw). The estimation of the yaw error angle is based on the Doppler shift measured on the received echo (first three plots for the Fore, Mid and Aft antenna) and aims to compute the correct acquisition geometry for the three Scatterometer antenna throughout the entire orbit. The Yaw error angle information is also used in the radar equation to derive the calibrated backscattering from the Earth surface and to select the echo samples associated to each node in the spatial filter. Read More Cyclone Archive The activities of cyclone tracking were interrupted at the end of September 2001. The data used for these cyclone tracking activities are ERS-2 Fast Delivery scatterometer data. Read More Telemetry Data This section provides information related to the acquisition of the instrument telemetry data. The data includes instrument working modes, temperatures, currents and voltages of the transmitter and calibration chain, and finally the antenna temperatures. Read More
