NUMBER 187

DATE: 02/09/99

Sector Processing Center (SPC):

During December, EUM, JMA, AES and CSU processed more than 97% of A data into B1/B2 data.

Normal operations for December were reported by EUM, JMA, AES and CSU.

NOA processing of B2 data is still on hold, pending receipt of new funding.

CSU is still supplying the AC data for GOES-8 until AES revises their format. AES has reported completion of this revision, but the new format has not be confirmed by the SCC.

Satellite Calibration Center (SCC):

AC data were received for December 98 from GOES-8, GOES-10, METEOSAT-5, METEOSAT-7, GMS-5 and NOAA-14 (AVHRR and HIRS). BC data for August 98 for GOES-10 and for October 98 for METEOSAT-5, METEOSAT-7 and GMS-5 were shipped to the GPC.

All BC reports now include normalization for the visible, standard infrared and "split-window" infrared channels (except METEOSAT which does not have a split-window channel), and the "water vapor" channels.

Global Processing Center (GPC):

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

The upgrade of the building network continues and the upgrade to the tape silo is now scheduled to begin in mid-February.

Production of NOAA-14 (preliminary) B3 data is current as of April 98; no further B2 data have been received. Final B3 data have been produced through April 98.

Production of NOAA-12 (preliminary) B3 data is current as of April 98; no further B2 data have been received. Final B3 data have been produced through April 98.

Production of GOES-7 (preliminary) B3 data is complete. Final B3 data have been produced through June 95.

GOES-8 B2 data deliveries are current. Development of the formatting software is underway.

GOES-9 B2 data deliveries are current; however, irregularities in the tape format have been discovered requiring replacement of the entire dataset to date. The formatting software has not been written yet.

Production of METEOSAT-5 (at 0) B3 data is complete. Final B3 data have been produced through December 95. Deliveries of B2 data from METEOSAT-5 (at 63E) are current.

Production of METEOSAT-6 (preliminary) B3 data is complete through June 98.

Production of METEOSAT-7 (preliminary) B3 data has not commenced; however, the formatting software has been completed.

Production of GMS-5 (preliminary) B3 data is current.

All B3 processing software and the B3 data formats have been revised to include, as of January 96, the normalization coefficients for all the additional spectral channels.

TOVS correlative data processing is complete through April 98.

Production of the ice/snow correlative dataset is complete through December 97.

DX/D1/D2 for January 84 - June 84 and for January 85 - December 85 have been processed. All of the old C1/C2 data have now been re-processed into D1/D2. The first CDrom of D2 data (for 89-93) has been released and is now available from the GPC or NASA Langley. Another CDrom of D2 data (for 83-88) will be prepared as soon as possible.

ISCCP Central Archive (ICA):

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

The health of GOES-8, GOES-10, GMS-5, METEOSAT-5, METEOSAT-7, NOAA-14 and NOAA-15 remained good. Collection of NOAA-12 data ceased in mid-December 98; collection of NOAA-15 data will commence as soon thereafter as possible. A report has been received that the Chinese FY-2 satellite has recovered to full operations sometime within the past two months.
