GRACE Monthly Report from May 2015 is available
The GRACE Science Data System Monthly Report from May 2015 is available now.
For Details see:
SDS Monthly Report May 2015.

Note: Highlights this month

* No RL05 Level-2 products could be generated and delivered for May 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 (see also section Level-1 Data Processing).
* The new ECMWF IFS (Integrated Forecast System) cycle 41r1, introduced on 11 May 2015, does not affect dramatically the quality of the AOD1B RL05 products. However, as in January 2006 and January 2010, again jumps at locations with high elevations have been detected since the orography resolution in the new cycle has been increased. In contrast to earlier reported plans to correct these jumps already during AOD1B generation, GFZ has decided to stay with the old procedure within RL05 (a-posteriori correction with Level-2 products) and will modify this approach starting with RL06 which is planned for autumn next year. Therefore GFZ will provide shortly a Level-2 GAG product (similar to GAE and GAF, as described in the current AOD1B Product Description Document V4.3 (will be updated accordingly)) to allow land users to correct this jump a-posteriori.
* The next GRACE Science Team Meeting is scheduled for September 21-23, 2015 in Austin. Further information will follow on the GSTM website at CSR at .
