NUMBER 159

DATE: 10/04/96

Sector Processing Center (SPC):

During August, NOA and JMA processed greater than 99% and CSU processed greater than 86% of A data into B1/B2 data. B1/B2 data from EUM for March and April 96 were shipped: 100% of the A data were processed for these two months.

Normal operations for August were reported by NOA and JMA. No reports were received from EUM and AES.

CSU reported that NOAA was testing the GOES-9 imager scan motor from 20 August through 2 September causing cancellation of images at 0600, 0900 and 1200 UTC each day for two weeks.

Satellite Calibration Center (SCC):

AC data were received for April and May 96 from GOES-8, for July 96 from METEOSAT-5 and GOES-9, and for August 96 from GOES-9, GMS-5 and NOAA-14. BC data for February, March and April 96 for GOES-8, GOES-9, METEOSAT-5 and GMS-5 were shipped to the GPC. As of January 96, BC data are being produced for every month. In addition, the additional IR channel for GMS-5, GOES-8 and GOES-9 at about 12 microns wavelength is being normalized to Channel 5 on the AVHRR. Normalization of the water vapor channel is still be investigated.

Global Processing Center (GPC):

The GPC continued to receive B2 data, BC data and correlative data in a routine manner.

Production of NOAA-14 (preliminary) B3 is current. Production of final B3 will require normalizing the calibration to the standard, NOAA-9.

Production of NOAA-12 (preliminary) B3 data is current. Final B3 data have been delivered through December 95.

Production of GOES-7 (preliminary) B3 data is complete. Final B3 data have been delivered through June 94.

GOES-8 B2 data through June 96; previous deliveries did not include the calibration block, so these data are being re-processed (and the format changed) to recover this information. The formatting software has not been written yet.

GOES-9 B2 data have not been delivered in final form, but a sample has been received by the GPC and is being checked. The formatting software has not been written yet.

Production of METEOSAT-3 (preliminary) B3 data is completed through January 95. The special CD-ROM datasets sent by ESA for February through April 95 have not been processed yet. Final B3 data have been delivered through June 94.

Production of METEOSAT-5 (preliminary) B3 data is current. Data through April 96 have been received. Final B3 data have been delivered through June 94.

GMS-5 B2 data deliveries are current, but formatting software has not been written yet. Production of GMS-4 (preliminary) B3 data is completed through May 95. Final B3 data have been delivered through June 94.

Final INSAT-1 B3 has been produced for the period April 88 through March 89.

TOVS correlative data processing has been completed through June 96.

Production of the ice/snow correlative dataset is complete through 94.

DX/D1/D2 processing continues to be slowed by work to upgrade the computer operating system. DX/D1/D2 for March, April and May 93 have been processed.

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. A new catalog of ISCCP data products was issued in June.
