Sudden Jump Algorithm in Operations

Date/Time Issued:
31 March 2010, 2330 UTC

31 March 2010

Date/Time of Expected End:

Possible major impact

Details/Specifics of Change:
On 31 March 2010, NOAA implemented the Sudden Jump Algorithm for all the AMSU-B and MHS L1B processing. As a reminder, NOAA did the same task for all the AMSU-A L1B processing on 5 May 2009 (see the related notice at http://www.osdpd.noaa.gov/data/ppp/notice_files/may0609.html). As a result, all the microwave L1B data are and will be processed with the Sudden Jump Algorithm.

For NK/NL/NM/NN/NP, the first orbits processed were:

NSS.HRPT.NK.D10090.S1540.E1554.B6177171.EB
NSS.GHRR.NK.D10090.S1719.E1846.B6177273.GC
