ISCCP PROJECT STATUS REPORT

NUMBER 181

DATE: 08/06/98

CENTER ACTIVITIES

Sector Processing Center (SPC):

During June, EUM, JMA, AES and CSU processed more than 93% of A data into B1/B2 data.

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

CSU completed delivery of the backlog of GOES-9 data covering the period from February 96 through March 97.

NOA continues to process the backlog of B2 data, shipping B2 data for January and February 98 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 June 98 from GOES-8, GOES-9, METEOSAT-6, GMS-5 and NOAA-14 (AVHRR and HIRS). BC data for April 98 for METEOSAT-6, GMS-5, GOES-8 and GOES-9 were shipped to the GPC.

Procedures to add normalization for METEOSAT-5 at 63?E, METEOSAT-7, and GOES-10 have been implemented.

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 February 98. 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 February 98. 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 January 95, spanning the calibration gap in late 94.

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

GOES-9 B2 data deliveries are current; the backlog of data for February 96 through March 97 has been received. The formatting software has not been written yet.

Production of METEOSAT-5 (preliminary) B3 data is complete. Final B3 data have been delivered through June 96.

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 April 98.

Production of the ice/snow correlative dataset is complete through December 96, after implementing new software to accommodate the new sea ice data source. Because of the

new software, these data are still being checked.

DX/D1/D2 for March, April, May and June 88 have been processed. Full production has resumed. Final contents of the 5-yr (89-93) CDrom version of the D2 data have been verified.

There are now 6.8 years of D2 data available: 1986 and March 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, GMS-5, METEOSAT-5, METEOSAT-7,

NOAA-12 and NOAA-14 remained good. NOAA-15 is being

checked out; it will replace NOAA-12. The momentum

wheel on GOES-9 is showing signs that it will fail,

so GOES-10 is being activated to replace GOES-9.

SCARAB-2 was successfully launched on the Russian

Resurs-01/4 on 10 July 98.
