ISCCP PROJECT STATUS REPORT

NUMBER 180

DATE: 07/02/98

CENTER ACTIVITIES

Sector Processing Center (SPC):

During May, EUM, JMA, AES and CSU processed more than 83% of A data into B1/B2 data.

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

NOA continues to process the backlog of B2 data, shipping B2 data for November and December 97 this month.

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 May 98 from GOES-8, GOES-9, METEOSAT-6, GMS-5 and NOAA-14 (AVHRR and HIRS). BC data for March 98 for METEOSAT-6, GMS-5, GOES-8 and GOES-9 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.

Production of NOAA-14 (preliminary) B3 data is current as of August 97. B2 data have been received through December 97. Final B3 data have been produced through December 96.

Production of NOAA-12 (preliminary) B3 data is current as of August 97. B2 data have been received through December 97. Final B3 data have been produced through December 96.

Production of GOES-7 (preliminary) B3 data is complete.

Final B3 data have been delivered through June 94. The calibration gap from September 94 through January 95, caused by loss of NOAA-11, has been eliminated, so production of final B3 data can resume.

GOES-8 B2 data deliveries are current. The formatting software has not been written yet.

GOES-9 B2 data for January 96 and for April 97 through May 98 have been delivered. The formatting software has not been written yet.

Production of METEOSAT-5 (preliminary) B3 data is complete. Final B3 data have been delivered through January 95.

Production of METEOSAT-6 (preliminary) B3 data is current.

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

TOVS correlative data processing has been completed through October 97.

Production of the ice/snow correlative dataset is complete through December 94. Snow data for 95, 96 and 97 have now been obtained. Sea ice data through June 97 have also been obtained.

DX/D1/D2 for July 88 have been processed. All the D-data for July through December 88 have now been delivered. Final contents of the 5-yr (89-93) CDrom version of the D2 data have been verified. Full production will resume this month: a production pace of 3-data months per week will be attempted, a pace of at least 2-data months per week should be possible.

There are now 6.5 years of D2 data available: 1986 and July 1988 through 1993. Samples are available on 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, EUM, CSU and JMA and B3 and C data from the GPC in a routine manner.

SATELLITE HEALTH

The health of GOES-8, GOES-9, GMS-5, METEOSAT-7, NOAA-12 and NOAA-14 remained good. METEOSAT-7 replaced METEOSAT-6 as the operational satellite on 3 June 98. Both METEOSAT-5 (at 63?E longitude) and METEOSAT-6 remain healthy. NOAA-K (now NOAA-15) was successfully launched on 13 May 98; once check-out is completed, it will replace NOAA-12.
