NUMBER 138
DATE: 01/13/95
Sector Processing Center (SPC):
During November, NOA, ESA, JMA, AES, and CSU processed greater than 84% of A data into B1/B2 data.
Normal operations for November were reported by ESA, JMA, and AES.
Following the failure of the NOAA-11 AVHRR in September, no NOAA-11 datasets are being produced by NOAA.
ESA reported a change of gain back to step 8 from step 9 for the METEOSAT-5 Water Vapor channel on 2 November 94 at 0800 UTC.
AES reported a much improved signal strength from GOES-7 allowing nearly complete collection of data for November.
CSU reported loss of a few days of METEOSAT-3 data while their antennae were re-configured to collect data from GOES-7. The re-configuration also allowed the beginning of GOES-8 data collection. The new configuration is, however, causing a large number of line drop-outs for the GOES-7 data. A change in the sampling procedure (to pick up the next line) was implemented to offset these losses. Full GOES-8 data collection is underway, even though GOES-8 is not yet operational.
Special Area Processing Center (SAPC):
No report received.
Satellite Calibration Center (SCC):
AC data were received for November 94 from METEOSAT-3 and METEOSAT-5. BC data for October 94 based on NOAA-12 for METEOSAT-3 and METEOSAT-5 were sent to the GPC, but only the infrared results were useable. The SCC also reported a successful transfer of GOES-7 AC data via Internet from CSU. The format developed will also be given to AES for transfer of their AC data.
Global Processing Center (GPC):
The GPC continued to receive B2 data, BC data and correlative data in a routine manner.
Production of NOAA-11 (preliminary) B3 data is complete. Final B3 data have been produced though February 93.
Production of NOAA-12 (preliminary) B3 data is current. Final B3 data for NOAA-12 have been produced through February 93.
Production of GOES-7 (preliminary) B3 data is current. The processing of the UWS replacement B2 data continues. The reported error in the GOES-7 IR calibration tables has been fixed and the B3 data through June 92 are being shipped to the ICA.
Production of METEOSAT-3 (preliminary) B3 data is current.
Production of METEOSAT-5 (preliminary) B3 data is current. Final B3 data for METEOSAT-4 have been produced through June 92.
Production of GMS-4 (preliminary) B3 data is current. Final B3 data for GMS-4 have been produced through August 92.
Production of all INSAT-1 (preliminary) B3 data has been completed.
Production of the ice/snow and TOVS correlative datasets is on hold. TOV processing stopped in March 94 and snow/ice processing is complete through 91. We have sea ice data through 92 and snow data through 93 and have made arrangements to get the sea ice data for 93 at the end of this month.
Routine re-processing, both forwards and backwards in time from 1 July 91 has commenced: June, July and August 91 are more than half completed.
ISCCP Central Archive (ICA):
The ICA continued to receive B1 data from NOA, AES, ESA, CSU and JMA and B3 and C data from the GPC in a routine manner.
The health of GMS-4, METEOSAT-3 (at 75 W), METEOSAT-5, GOES-7 and NOAA-12 remained good. Check out of GOES-8 continues, but nearly routine operations have commenced. GOES-7 is moving towards 135W and GOES-8 will begin moving towards 75W after check-out is completed. There is no information about the status of ELEKTRO. The launch of NOAA-14 was successfully completed on 30 December 94 after many delays caused by weather. Although there were some early problems, operations were handed over to NOAA this month and check-out is expected to be completed by 20 January. NOAA-14 will replace NOAA-11. The problems with the METEOSAT-6 radiometer appear to be decreasing with time; one more attempt to remove what is thought to be water contamination will be made. GMS-5 was scheduled for launch in Japan on 1 February 95, but the launch has been delayed by problems with the companion payload.
Stage B3: July 83 - June 92
Stage CD: July 83 - December 91
Stage C1: July 83 - June 91
Stage C2: July 83 - June 91
Delivering sea ice correlative data for 93 to GPC.
Delivery backlog for B3 data = 23 months (with respect to planned schedule). B3 data for 108 months have been archived.
Delivery backlog for C1/C2 data = 35 months (with respect to planned schedule). C1 data for 96 months have been archived.
