Sector Processing Center (SPC):

During July, NOA, ESA, CSU and JMA processed greater than 92% of A data into B1/B2 data.

Normal operations for June were reported by NOA, ESA and JMA.

CSU reported direct collection of 45% of GOES-7 data; losses continue because of the large orbital motions of the satellite. However, almost all of the lost data have been obtained from NASA Ames (total of 97% obtained for July). Similarly, over 90% of the data for June have been obtained.

Satellite Calibration Center (SCC):

AC data were received for May, June and July 95 from GOES-7 and for July 95 from GMS-5 and METEOSAT-5. Also AC data for GOES-8 for January through June 95 (no data available in February) were received. Problems were reported with the format of the AC data received from AES and are being investigated.

Global Processing Center (GPC):

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

Production of NOAA-11 B3 data is completed through September 94.

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 requires normalizing the calibration to NOAA-11 and then 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 December 93.

GOES-8 B2 data are now being received routinely, but 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 June 93.

Production of METEOSAT-5 (preliminary) B3 data is current. Final B3 data for METEOSAT-4 have been produced through December 93.

Production of GMS-4 (preliminary) B3 data is completed through May 95. Final B3 data have been produced through December 93.

The first GMS-5 B2 data for June and July 95 have been received.

Production of all INSAT-1 (preliminary) B3 data has been completed. Final INSAT-1 B3 has also been produced for the period April 88 through March 89. Other data could not be reliably calibrated.

TOVS correlative data processing is current. The revised version of the whole TOVS dataset will be delivered once documentation has been completed.

Production of the ice/snow correlative dataset has been completed through 93; processing of 94 awaits the last month of data from NSIDC. The revised version of the whole ice/snow dataset will be delivered once documentation has been completed.

DX/D1/D2 data production continues; data for February, March, April and May 90 have been completed. With the completion of the ice/snow datasets, processing will focus on the period January 92 - August 94 (up to the failure of NOAA-11) and then re-process data from before 1990. Deliveries of DX/D1/D2 will begin once the documentation is completed.

A complete version of the C1/C2 data document and the 1995 revised calibration tables have been posted to the ISCCP Home Page. The updated version of the calibration document will be posted shortly.

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-7, GOES-8, NOAA-12 and NOAA-14 remained good. GOES-9 may become operational in October 95.

Stage B3: July 83 - June 93

Stage CD: July 83 - December 91

Stage C1: July 83 - June 91

Stage C2: July 83 - June 91

Delivery backlog for B3 data = 19 months (with respect to planned schedule). B3 data for 120 months have been archived.

Delivery backlog for new DX/D1/D2 data = 43 months (with respect to planned schedule). C1 data for 96 months have been archived.
