NUMBER 151

DATE: 02/06/96

Sector Processing Center (SPC):

During December, NOA, CSU and JMA processed greater than 95% of A data into B1/B2 data.

Normal operations for December were reported by JMA. No formal report was received from EUM (EUMETSAT), but they indicated no operational problems.

The NOAA SPC and ICA are still recovering from the two US Government shutdowns and a record-breaking blizzard. There were two other days lost due to subsequent storms.

AES reported beginning operational collection of GOES-8 data in late January, although still in a test mode.

CSU collected all of the GOES-7 data for December from its alternate source. CSU corrected a pixel-alignment error in GOES-8 data since July 95 and replaced the B1 and B2 data for September through November 95. Collection of GOES-9 has commenced.

Satellite Calibration Center (SCC):

AC data were received for November 95 from NOAA-14 and GMS-5 and for December 95 from GMS-5, GOES-7 and GOES-8. BC data for February and April 95 for GMS-5 were replaced to correct an error. BC data for February and April 95 for GOES-7 were also shipped to the GPC.

Global Processing Center (GPC):

Due to another U.S. Government shutdown for 22 days in December and early January, plus a major blizzard, less data processing occurred at the GPC than usual.

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

Production of NOAA-12 (preliminary) B3 data is current. Final B3 data have been produced through December 94.

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

Production of GOES-7 (preliminary) B3 data is completed through November 94. Merger of several sources of data beyond November will be required. Final B3 data have been produced through August 94.

GOES-8 B2 data are now being received routinely, but 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 produced through August 94.

Production of METEOSAT-5 (preliminary) B3 data is current. Final B3 data have been produced through August 94. Some replacement data have been received from EUM and the format confirmed.

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

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

TOVS correlative data processing has been completed through 94. The revised version of the whole TOVS dataset (July 83 - December 95) will be delivered this month.

Production of the ice/snow correlative dataset has been completed through 93. The revised version of the whole ice/snow dataset (July 83 - December 94) will be delivered this month.

DX/D1/D2 data production continues: data for May and June 93 for the BALTEX project have been completed, data for May and June 86 have been completed for the Surface Radiation Budget project. The DX/D1/D2 data were released upon completion of documentation: three years, 1990, 1991, 1992, are now available.

Documentation of the Stage D datasets and the revised TOVS and ice/snow correlative datasets has been posted to the ISCCP Home Page. The ISCCP World Wide Web Home Page can be accessed at URL

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-5, METEOSAT-5, GOES-8, GOES-9, NOAA-12 and NOAA-14 remained good. GOES-7 operations were terminated in January.

Stage B3: July 83 - June 9 (11.0 years)

Stage CD: July 83 - December 91 ( 8.5 years)

Stage C1: July 83 - June 91 ( 8.0 years)

Stage C2: July 83 - June 91 ( 8.0 years)

Stage D1: January 90 - December 92 ( 3.0 years)

Stage D2: January 90 - December 92 ( 3.0 years)

Delivery backlog for B3 data = 12 months (with respect to planned schedule). B3 data for 132 months have been archived.

Delivery backlog for new DX/D1/D2 data = 30 months (with respect to planned schedule). C1/C2 data for 96 months have been archived. D1/D2 data for 36 months have been archived.
