NUMBER 103

DATE: 03/04/92

Sector Processing Center (SPC):

During January, NOA, JMA, and ESA processed greater than 98% of A data into B1/B2 data.

Normal operations were reported by NOA, JMA and ESA. No reports have been received from AES for December and January.

CSU reported that collection of METEOSAT-3 (at 50W) data continues to be a rapidly evolving problem as NOAA changes its plans for dissemination of the data. Currently, these data are disseminated through GOES-6 which can be seen by the CSU antennas; however, NOAA is planning to switch to distribution by a domestic communication satellite (DOMSAT) and to begin broadcasting its new GOES data format through GOES-6 on an experimental basis. However, this new format broadcast is not "full-time", so it is not an option. CSU is purchasing the equipment to receive the DOMSAT signal, so it will switch to this method in June. Meanwhile, it appears that NOAA has been persuaded to continue transmissions through GOES-6 in the old format, at least through April, and may be convinced to continue through June. Image and format schedules are not final, but currently they may cause the loss of the "local noon" images. Negotiations are on-going.

CSU also reported that work is underway to complete the last of the INSAT B2 data (January - April 89) for delivery to the GPC.

Special Area Processing Center (SAPC):

No reports were received.

Satellite Calibration Center (SCC):

The SCC reported receipt of AC data for January 92 for GMS-4, METEOSAT-3, METEOSAT-4 and NOAA-11. BC data for MET-3 for October 91 were sent to the GPC.

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 current. Re-calibration of NOAA-11 B3 data has been completed through November 91 and the data through June 91 have been shipped to the ICA.

Production of NOAA-12 (preliminary) B3 data is current.

Production of METEOSAT-4 (preliminary) B3 data is current. Re-calibration of METEOSAT-4 B3 data has been completed through April 91 and the data through December 90 have been shipped to the ICA.

Production of GOES-7 (preliminary) B3 data is current (with some problems still in July and August 91 B2 data). Re-calibration of GOES-7 B3 data has been completed through November 90 and the data through June 90 have been shipped to the ICA.

Production of GMS-4 (preliminary) B3 data is current. Re-calibration of GMS-4 B3 data has been completed through June 91 and the data shipped to the ICA.

Production of INSAT-1 (preliminary) B3 data has been completed from January 86 through December 88.

Production of TOVS and the ice/snow correlative datasets is current.

C1 data for May and June 90 have been completed and delivered to the ICA. Small calibration errors in data for April 85 and October - December 89 were corrected and new versions of these data shipped to the ICA. The C2 data for 89 were also completed and shipped.

THE FIRST SEVEN YEARS OF C1 DATA HAVE BEEN COMPLETED!

ISCCP Central Archive (ICA):

The ICA continued to receive B1 data from NOA, AES, ESA, and JMA and B3 and C data from the GPC in a routine manner.
