NUMBER 104

DATE: 04/03/92

Sector Processing Center (SPC):

During February, NOA, JMA, and ESA processed greater than 98% of A data into B1/B2 data.

Normal operations were reported by NOA, JMA and ESA. No reports have been received from AES for December, January and February.

ESA reported replacing METEOSAT-4 with METEOSAT-5 as the operational satellite from 0900 UTC on 11 February through 0830 on 25 February.

Special Area Processing Center (SAPC):

No reports were received.

Satellite Calibration Center (SCC):

The SCC reported receipt of AC data for February 92 for GMS-4 and for October 91 - February 92 for GOES-7. No BC data were sent.

Global Processing Center (GPC):

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

Production of NOAA-11 (preliminary) B3 data is current. Re-calibration of NOAA-11 B3 data has been completed through December 91 and the data have been shipped to the ICA.

Production of NOAA-12 (preliminary) B3 data is current.

Production of METEOSAT-4 (preliminary) B3 data is current. Re-calibration of METEOSAT-4 B3 data has been completed through June 91 and the data have been shipped to the ICA.

Production of GOES-7 (preliminary) B3 data is current (with some problems still in July and August 91 B2 data). Re-calibration of GOES-7 B3 data has been completed through June 91 and the data have been shipped to the ICA.

Production of GMS-4 (preliminary) B3 data is current.

Production of INSAT-1 (preliminary) B3 data has been completed from January 86 through December 88.

ALL OF THE B3 DATA (WITH THE EXCEPTION OF INSAT) HAVE BEEN COMPLETED AND SHIPPED FOR JULY 83 THROUGH JUNE 91.

Production of TOVS and the ice/snow correlative datasets is current. TOVS data for 91 have been completed and shipped to the ICA.

Special CX (pixel-level ISCCP results) datasets are being produced to support various other projects. A special dataset for April 89 for eleven sites was produced for the Surface Radiation Budget project comparison of surface radiative flux algorithms. Since the FIRE CIRRUS I datasets were delivered without the final calibration, these datasets have been re-done (the changes only involve the individual adjustments to the GOES-6 IR calibration on an image-by-image basis and are quite small). Special datasets are being produced for FIRE MARINE STRATUS I, ICE I, ICE II, and FIRE CIRRUS II.

C1 data for July, August, September, October and November 90 have been completed; C1 data through August 91 have been delivered to the ICA. Production of C1/C2 data will stop after December 90 is completed because the NAVY/NOAA Sea Ice dataset for 91 has not been delivered yet. As soon as these data are received, production will resume.

Current plans are to cease production of this version of the C1/C2 data with June 91, giving an eight year climatology (although, if NOAA-12 normalization can be completed, it is tempting to finish 91 data despite effects of Pinatubo). Re-processing to produce the new version of C1/C2 will commence in late summer.

ISCCP Central Archive (ICA):

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