1. WP 2.3 Change in mass balance of the Green-
land ice sheet and its transfer to sea level rise
D 2.3.1:– Time series of satellite altimetry height changes of the Greenland ice sheet, year since 1992 expressed as height change grids - month 18
D 2.3.2: Grid of ICESat height changes, average trend month 18
D 2.3.3: Gridded time series of GRACE-based Greenland mass changes - month 18
D 2.3.4: Time series of Greenland ice sheet mass balance from 1992 to present (combining all techniques) and improved ”overall” freshwater input trend to the oceans surrounding Greenland and sea level rise - month 36
MONTH 18 = end of August 2011

2. WP 2.3: Status and questions
Deadlines for upcoming deliverables D2.3.1-D2.3.3 are due MONTH 18, this is at the end of August, 2011:
Lead beneficiary: DTU Space
D 2.3.1: Time series of satellite altimetry height changes of the Greenland ice sheet, year since 1992 expressed as height change grids 
-              I believe this is covered by input from NERSC based on ERS-1/2 and ENVISAT data ?
D 2.3.2: Grid of ICESat height changes, average trend
-              This deliverable is almost ready

3. WP 2.3: Status and questions - continued
Lead beneficiary: CNRS
D 2.3.3: Gridded time series of GRACE-based Greenland mass changes
-              Are these mass changes provided by CNRS and/or DTU Space ?
D 2.3.4: Time series of Greenland ice sheet mass balance from 1992 to present (combining all techniques) and improved ”overall” freshwater input trend to the oceans surrounding Greenland and sea level rise - month 36
-              Are there any wishes for the division of the Greenland ice sheet for the freshwater flux outlet basins ?
Last but not the least we need to agree on data format and grid definitions.
