ERS-2 Scatterometer L2 dataset processing with ASPS v. 10.04 completed
14 May 2015
The re-processing campaign of ERS-2 Scatterometer Level 2.0 products has been completed, adopting the latest Advanced Scatterometer Processing System (ASPS) version 10.04. Data from Cycle 10 to Cycle 165 (26 March 1996 - 07 March 2011) and from the 3 days repeat cycles at the end of the mission (07 March 2011 - 05 July 2011) is now available to the user community.
Detailed information related to the ERS-2 Scatterometer consolidated Level 2.0 products availability can be found here.
The new ASPS Level 2 data set includes significant quality improvements with respect to the previous near-real time UWI data version:
In addition, the long-term ERS-2 dataset has also been characterised in terms of CMOD5N geophysical forward model derived by ECMWF in order to retrieve the neutral winds from the backscattering measurements.
The ASPS Level 2 products are available in nominal resolution of 50km (ASPS20_N) and in high resolution of 25 Km (ASPS20_H). In addition, the ERS data reprocessed with the ASPS v 10.04 facility is also available in the UWI format in order to maintain the compatibility with the previous operational data format. The detailed description of the product format is reported in the Product Specification document.
The latest reprocessed data is made available online via FTP together with the previously released products. For new users, access can be provided through Fast Registration.
The ERS-2 Scatterometer ASPS data will be moved to the ESA centralised dissemination server within 2015. Users will be informed about the change of credentials in due time.
More detailed information on all changes implemented for the reprocessing campaign with ASPS version 10.04 is available on the ESA Sensor Performance and Product Algorithm portal:
