NUMBER 232 DATE: 11/11/02

Sector Processing Center (SPC):

During September, EUM, JMA, CSU, and NOA processed more than 99% of A data into B1/B2 data. No report was received from MSC.

Normal operations for September were reported by EUM, JMA, CSU and NOA.

CSU is still supplying the AC data for GOES-8 because the SCC has not accepted the revised format from MSC.

Satellite Calibration Center (SCC):

AC data were received for September 02 from NOAA-16 (AVHRR and HIRS), METEOSAT-5, METEOSAT-7, GMS-5, GOES-8 and GOES-10. BC data for July 02 for METEOSAT-5, METEOSAT-7, GMS-5, GOES-8 and GOES-10 were shipped to the GPC. The delayed processing of the normalization for the "water vapor" channels to NOAA-16 HIRS is now complete through April 02.

All AC data are now received via Internet.

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 by Internet. All data products (except DX) from the GPC are delivered by ftp to NOAA/NCDC and to NASA Langley.

Deliveries of B2 data from NOAA-16 are current. A prototype formatter code, which neglects the 1.6 micron channel data, has been written and all of the NOAA-16 B2 data processed into a preliminary form of B3 data to allow for calibration analysis.

Deliveries of B2 data from NOAA-17 are current.

Deliveries of B2 data from GOES-8 are current. Production of GOES-8 (preliminary) B3 data is complete through September 01. Final B3 data have been produced through September 01.

Deliveries of B2 data from GOES-10 are current. Production of GOES-10 (preliminary) B3 data is complete through September 01. Final B3 data have been produced through September 01.

Deliveries of B2 data from METEOSAT-5 (at 63E) are current. Production of METEOSAT-5 (preliminary) B3 data is complete through September 01. Final B3 data have been produced through September 01.

Deliveries of B2 data from METEOSAT-7 are current. Production of METEOSAT-7 (preliminary) B3 data is compete through September 01. Final B3 data have been produced through September 01.

Deliveries of B2 data from GMS-5 are current. Production of GMS-5 (preliminary) B3 data is complete through September 01. Final B3 data have been produced through September 01.

Deliveries of TOVS correlative data are current. TOVS processing is complete through September 01. A format change in TOVS occurred in October 01, so the processing software will have to be modified.

Deliveries of snow/ice correlative data are current. Production of the snow/ice dataset is complete through December 01.

DX/D1/D2 data processing is complete through September 01. An investigation to identify all small processing/calibration errors continues.

Two CDs of D2 data are now available from NASA Langley, covering 83-88 and 89-93. A new CD covering 94-98 has now been released.

The entire D2 dataset is now available on the ISCCP Web site. Browse data now available on the Web site are monthly mean data for July 83 through September 01 and climatology results based on the period July 83 through September 01. The radiance calibration tables have been updated through September 01. All of the documentation has been brought up to date. Two new datasets have been added to the Web site: the first is a browse version of the cloud climatology based on Surface Weather Observations covering the period December 1981 through November 1991. The complete, more detailed dataset is now supported by a new Web site (http://www.atmos.washington.edu/~ignatius/CloudMap, which has the newly revised climatology for land available. The second dataset illustrates the monthly mean results from the calculations of top-of-atmosphere, in-atmosphere and surface radiative fluxes covering the entire ISCCP data record (July 1983 - June 2001). These radiative fluxes have the same space and time resolution as the ISCCP D1 dataset. 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, MSC, 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-16 and NOAA-17 remained good. METEOSAT-6, GOES-11 and GOES-12 are in stand-by mode. GOES-12 is now scheduled to replace GOES-8 at the end of March 03. GOES-9 will replace GMS-5 at the about the same time until MTSAT-1R can be launched next year. China plans the launch in 2005 of the first of its new polar orbiting weather satellites, called FY-3; the payload will include a 20-channel imager, a 26-channel infrared sounder, a 10-channel scanning radiometer, a 12-channel microwave imager and a 4-channel microwave radiometer.
