NUMBER 219 DATE: 10/10/01

Sector Processing Center (SPC):

During August, EUM, JMA, CSU, MSC and NOA processed 98% of A data into B1/B2 data.

Normal operations for August were reported by EUM, JMA, CSU, MSC and NOA. JMA reported completion of the re-processing of B2 data for July and August to make the needed image substitution.

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 August 01 from NOAA-14 (AVHRR and HIRS), METEOSAT-5, METEOSAT-7, GMS-5, GOES-8 and GOES-10. BC data for June 01 for METEOSAT-5, METEOSAT-7, GMS-5, GOES-8 and GOES-10 were shipped to the GPC.

AC data for GMS are received on 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, the B2 data from MSC and CSU, and the correlative data, which are received via Internet. The ftp delivery of B2 data by EUM is still being tested. JMA reported that they will soon be ready to begin ftp delivery of data. Delivery by ftp of all data (except DX) from the GPC to NOAA/NCDC and to NASA Langley is now underway.

Deliveries of B2 data from NOAA-14 are current. Production of NOAA-14 (preliminary) B3 data is complete through December 00. Final B3 data have been produced through December 00. NOAA-14 will remain the primary calibration reference for ISCCP because we have a much longer history for it than for NOAA-16.

NOAA-15 B2 data have been received for January 99 through July 00 (the last). The revised formatting software for NOAA-15 data has been completed and is now being tested.

Deliveries of B2 data from NOAA-16 are current. Processing will require more extensive software changes than for NOAA-15 because of the six channels available.. Also, the cloud detection algorithm and the DX-format will have to be revised before these data can be used.

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 99.

Deliveries of B2 data from GOES-10 are current. Production of GOES-10 (preliminary) B3 data is complete through December 99. Final B3 data have been produced through December 99.

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

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

TOVS correlative data processing is complete through June 00.

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

DX/D1/D2 data processing is complete through December 98. All of the D data for 95 through 98 have been re-processed to correct the VIS calibration. Delivery of D data for 95 through 97 was delayed but has now resumed. All data products are currently delivered by ftp to the ICA and NASA Langley (except for DX data).

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

The full survey of midlatitude cyclones is underway.

A new set of plots for the monthly report, indicating satellite and dataset processing status, is being released this month.

Data now available on the Web site are monthly mean data for July 83 through December 97 and climatology results based on the period July 83 through December 97. The radiance calibration tables have been updated through December 00. A new dataset released is the preliminary survey of cloud particle sizes (effective radius) for both liquid and ice clouds. Planning is underway to add the cloud climatology based on surface weather observations to the ISCCP Web site. 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-14 and NOAA-16 remained good. METEOSAT-6 and GOES-11 are in stand-by mode. As of March 01, NOAA-16 is the primary "afternoon" polar orbiter, but NOAA-14 continues parallel operations. The start of FY-2B operations was planned to occur in January 01, but no report has been received. GMS-5 scan motor problems continue; although the frequency of whole-Earth images has been reduced to prevent sticking, the main 3-hr images required by ISCCP are still collected. GOES-12 check-out is complete; it will replace GOES-8 in January 02.

Stage B3: July 83 - December 99 (16.5 years)

Stage TV: July 83 - December 99 (16.5 years)

Stage SI: July 83 - December 99 (16.5 years)

Stage D: July 83 - December 98 (15.5 years)
