NUMBER 213 DATE: 04/06/01

Sector Processing Center (SPC):

During February, EUM, JMA, CSU and MSC processed 100% of A data into B1/B2 data (a first after almost 18 years!).

Normal operations for February were reported by EUM, JMA, CSU and MSC.

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

Satellite Calibration Center (SCC):

AC data were received for February 01 from NOAA-14 (AVHRR and HIRS), METEOSAT-5, METEOSAT-7, GMS-5, GOES-8 and GOES-10. BC data for December 00 for GOES-8, GOES-10, METEOSAT-5, METEOSAT-7 and GMS-5 were shipped to the GPC.

Re-processing of the WV channel normalization for GOES-8 has been completed. Re-processing of the GOES-9 WV channel normalization is completed.

Currently, AC data for GMS are the only ones received on media (CD-rom); all other AC data are received and the BC data are sent 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; all of these data are currently received on media, except for the BC data and the B2 data from MSC, which are received via Internet. The ftp delivery of B2 data by CSU is ready to begin and final testing of the arrangements for ftp delivery of B2 data by EUM are underway. Delivery by ftp of all data (except DX) from the GPC to NASA Langley is ready. Final details of the dataset naming convention are being worked out with NOAA/NCDC. TOVS data are being obtained from NOAA/NCDC by ftp.

Porting of all the ISCCP processing software to workstations is complete. A complete code review is planned for spring. Final migration of some datasets from mainframe-compatible media to workstation-compatible media is ongoing.

NOAA-14 B2 data have been received through April 00. Production of NOAA-14 (preliminary) B3 data is complete through April 00. Final B3 data have been produced through April 98, but the calibration has been extended through April 00. As has happened before, the precise VIS calibration changes somewhat when a longer record is analyzed. In this case, the normalization to NOAA-9 changed from 1.164 with a trend correction of 1.00015 per month to a normalization of 1.120 and a trend correction of 1.00168 per month.

Production of NOAA-12 (preliminary) B3 data is complete through December 98 (the last). Final B3 data have been produced through April 98, but the calibration has been extended through December 98..

NOAA-15 B2 data have been received for January 99 through July 00 (the last). Because of the changes in spectral response (visible channel) and the switching of channels (for channel 3), both the calibration procedure and the B3 processing software will have to be revised for NOAA-15 processing. Also, the cloud detection algorithm will have to be revised before these data can be used.

GOES-7 B3 data for the period January 94 through December 95 have been re-processed to include some VIS data excluded in the original processing because the definition of day and night images was not consistent with the actual situation at that time.

Deliveries of B2 data from GOES-8 are current. Production of GOES-8 (preliminary) B3 data is complete through December 99. Final B3 data have been produced through December 97.

All (January 96 through July 98) GOES-9 B3 have been produced in final form and delivered to the ICA

Deliveries of B2 data from GOES-10 are current. The formatting software is ready.

Deliveries of B2 data from METEOSAT-5 (at 63E) are current. Production of METEOSAT-5 (preliminary) B3 data is complete through December 99.

Production of METEOSAT-6 (preliminary) B3 data is complete through June 98. Final B3 data have been produced through April 98.

Deliveries of B2 data from METEOSAT-7 are current. Production of METEOSAT-7 (preliminary) B3 data is compete through December 99.

Deliveries of B2 data from GMS-5 are current. Production of GMS-5 (preliminary) B3 data is complete through December 99. Final B3 data have been produced through December 97.

TOVS correlative data processing is complete through April 98. An error in the TOVS processing has been discovered that causes somewhat inaccurate temperatures to be reported near the surface and the tropopause in the monthly-mean files that are used to fill in missing observations. This error has been corrected and the TOVS data for 94 through 97 have been re-processed.

Production of the ice/snow correlative dataset is complete through December 99.

DX/D1/D2 data processing is now ready to start: all calibration anomalies and processing problems have been resolved. Starting with the 94 data, the small error in the retrieval of cloud top temperatures will be corrected. All data products are currently delivered on media to the ICA, but are delivered by ftp to NASA Langley.

Two CDs of D2 data are now available from NASA Langley, covering 83-88 and 89-93.

Data now available on the Web site are monthly mean data for July 83 through December 93 and climatology results based on the period July 83 through June 94. 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 and NOAA-14 remained good. METEOSAT-6 and GOES-11 are in stand-by mode. NOAA-16 is operating in parallel with NOAA-14. The start of FY-2B operations was planned to occur in January 01, but no report has been received.

Stage B3: July 83 - December 97 (14.5 years)

Stage CD: July 83 - December 97 (14.5 years)

Stage D1: July 83 - August 94 (11.2 years)

Stage D2: July 83 - August 94 (11.2 years)

* Delivery backlogs for B2 data (NOAA-14 = 10 months).

* Delivery backlog for B3 data = 32 months (with respect to planned schedule). B3 data for 174 months have been archived.

* Delivery backlog for DX/D1/D2 data = 72 months (with respect to planned schedule). D1/D2 data for 134 months have been archived.
