Details/Specifics of Change
On 11 June around 1952Z, NOAA-19 MHS cold bias corrections were placed into operations. The new values were provided by Eumetsat to correct errors seen in the current data, particularly in channel 1. The new values of the cold bias corrections (in K) are as follows,
Ch.1 Ch.2 ch.3 ch.4 ch.5 Profle
-------- ------- ------ ----- ------ -------
1.18 0.69 0.91 0.91 0.54 0
1.50 0.77 0.99 0.99 0.57 1
1.12 0.64 0.82 0.82 0.46 2
-------------------------------------------------
The first orbits to be processed with the new values are:
NSS.HRPT.NP.D09162.S2038.E2052.B0176868.GC
NSS.GHRR.NP.D09162.S1839.E2034.B0176668.GC
