NUMBER 140

DATE: 03/09/95

Sector Processing Center (SPC):

During January, NOA, ESA, and JMA processed greater than 97% of A data into B1/B2 data, while AES processed 71% of GOES-7 A data into B1/B2 data and CSU processed 87% of GOES-7 A data and 71% of METEOSAT-3 A data into B1/B2. In December CSU processed 92% of GOES-7 and 93% of METEOSAT-3 A data into B1/B2.

Normal operations for January were reported by ESA and JMA.

NOAA began collection of NOAA-14 data on 18 January 95.

AES reported continued weak signal from GOES-7 causing the loss of about 30% of the data in January.

CSU reported normal collection of METEOSAT-3 in December, but degraded collection during January as METEOSAT-3 drifted eastward towards 70W. Collection of METEOSAT-3 has ended, so that the antennas can be re-configured for GOES-8 collection. CSU collected more than 91% of GOES-7 data in December and more than 86% in January. The line-drop problem continues, but the new collection procedure (take the next line) seems to work well. GOES-7 has now reached its new station at 134.7W.

Special Area Processing Center (SAPC):

No report received.

Satellite Calibration Center (SCC):

AC data were received for December 94 from METEOSAT-3 and METEOSAT-5 and for January 95 from METEOSAT-3, METEOSAT-5, GMS-4 and NOAA-12. Collection of NOAA-14 AC has begun. BC data for November 94 from GOES-7 based on NOAA-12 were sent to the GPC. These results were based on AC data from both AES and CSU. Comparison of the normalization obtained from the two days of common data showed excellent results for the infrared -- the visible results were not too good because there were few cloud present.

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 June 93.

Production of NOAA-12 (preliminary) B3 data is current. Final B3 data have been produced through June 93.

Production of GOES-7 (preliminary) B3 data is current. The processing and merger of the UWS replacement B2 data has been completed. Final B3 data have been produced through June 92.

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 93.

Production of GMS-4 (preliminary) B3 data is current. Final B3 data have been produced through June 93.

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. We thought we were about to get the 93 sea ice but new problems have arisen -- stay tuned.

Routine DX/D1/D2 re-processing continues: May, September and October 91 have been completed. Deliveries of DX/D1/D2 will begin once the documentation is 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, GOES-8 and NOAA-12 remained good. METEOSAT-3 is moving eastward to make room for GOES-8; but collection of METEOSAT-3 data has ceased. GOES-7 has reached 135W and GOES-8 is moving towards 75W. NOAA-14 began operations in mid-January 95. Launch of GMS-5 has not been rescheduled.

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 = 25 months (with respect to planned schedule). B3 data for 108 months have been archived.

Delivery backlog for C1/C2 data = 37 months (with respect to planned schedule). C1 data for 96 months have been archived.
