GRACE Technical Note 07

TITLE: Monthly estimates of C20 from 5 SLR satellites based on GRACE RL05 models.

UPDATE HISTORY: Created April 3, 2013 - last month reported is February 2013.

SPECIAL NOTES:
        Please use these estimates to replace the C20 values from the GSM
        files of the GRACE RL05 products only. These estimates should not
        be used with the GRACE RL04 or earlier products. In particular, a
        rate for C20 has not been modeled for RL05, whereas a rate was
        modeled for RL04.

        1) The GRACE gravity solution from CSR for 'November 2011' actually
        spans October 17, 2011 to November 16, 2011, due to the lack of
        useful accelerometer data in the latter half of November. A
        replacement value of C20 is provided for this special solution
        (denoted by *) as well as for the full calendar month of November 2011. 

        2) The GRACE gravity solution from CSR for 'December 2011' actually
        spans December 12, 2011 to January 11, 2012, due to the lack of
        useful accelerometer data in the first half of December. A
        replacement value of C20 is provided for this special solution
        (denoted by *) as well as for the full calendar month of December 2011. 

        3) The GRACE gravity solution from CSR for 'April 2012' actually
        spans March 20, 2012 to April 19, 2012, due to the lack of
        useful accelerometer data in the latter half of April. A
        replacement value of C20 is provided for this special solution 
        (denoted by *).
