On April 17, 2001, the following update will go into operation for
NOAA-16 Level-1B:
We will switch the level 1B process to correct the along track error
using a +1 second in addition to the normal clock error. The user will
see changes in the earth location data that will improve the quality
with the clock correction offset reflecting a different range from
current. Also, the attitude correction information will become zero
with the constant attitude correction flag set to zero in the header
record.
The change will be made between the hours of 11:00am and 12:30 pm
local. The last passes processed before the change will be:
NSS.LHRR.NL.D01107.S0919.E0926.B0293333.GC
NSS.HRPT.NL.D01107.S1447.E1502.B0293636.GC
NSS.GHRR.NL.D01107.S1300.E1447.B0293536.GC
All data with time periods after the above passes will be processed
using
the changes.
Please contact us if you have any questions or concerns.
Thank you.
