News related to GRACE Gravity Data

This page is regularly updated and contains important news about GRACE data products as well as useful hints how to use the most recent GRACE RL02 Level-1B and RL05 Level-2 data. Additional information may also be taken from the monthly GRACE SDS newsletters.

2016

June 2016:

  • No RL05 Level-2 products could be generated and delivered for April 2016 due to planned switch-offs of the GRACE-A and GRACE-B Microwave Assemblies (MWA) and Instrument Control Units (ICU) in order to reduce the load on the batteries.
  • Due to a processing bug, the originally published GFZ Level-2 GSM product for February 2016 (labelled ‘GSM-2_2016029-2016060_0032_EIGEN_G---_005a‘) turned out to be erroneous. A correct product has been generated which has replaced the previous wrong one in the GRACE archives ISDC and PO.DAAC. Please make sure that you use the correct version of the GSM product for February 2016. This can be checked by looking at the product generation date (to be found in the record ‘FIRST’ of the Level-2 product file) which should be ‘20160615’. Note that only the GSM files (*.gz and *.txt) are affected; the corresponding GAx products remain unchanged.

May 2016:

  • Note that the RL05 Level-2 products for February 2016 generated and delivered by CSR, GFZ and JPL are based on 32 days of data between January 29 and February 29.

March 2016:

  • Note that the RL05 Level-2 products for January 2016 generated and delivered by CSR, GFZ and JPL are based on 25 days of data between January 4  and January 28.

February 2016:

  • Note that the RL05 Level-2 products for December 2015 generated and delivered by CSR, GFZ and JPL are based on 24 days of data between December 11  and January 3.

January 2016:

  • No RL05 Level-2 products could be generated and delivered for November 2015 due to planned switch-offs of the GRACE-A and GRACE-B Microwave Assemblies (MWA) and Instrument Control Units (ICU) in order to reduce the load on the batteries.
