MERRA Current Status

4/19/2007

The science aspect of the MERRA is frozen. There are some final settings in the system that are awaiting a final decision. Validation of the whole system should be under way in 1-2 weeks.

This is an example of the precipitation being produced in the system.

The figure shows the difference of monthly reanalysis precipitation from GPCP. The numbers over each panel show the mean global difference (near zero is good) and the global standard deviation of the difference (smaller is better).

MERRA Introduction

NASA's Modern Era Retrospective-analysis for Research and Applications (MERRA) is intended to be a full reanalysis of the satellite era. In general, the data provided will support science research and applications.

The official MERRA WWW site is: http://gmao.gsfc.nasa.gov/merra/

This Blog is intended to be an interface between the developers and user community, and a place for status updates and Q&A regarding the MERRA production and data.
