NUMBER 217 DATE: 08/03/01

Sector Processing Center (SPC):

During June, EUM, JMA, CSU, MSC and NOA processed 97% of A data into B1/B2 data.

Normal operations for June were reported by EUM, JMA, CSU, MSC and NOA. NOAA-14 data for March through June 01 were sent to the GPC; NOAA-16 data for March 01 were also sent.

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 June 01 from NOAA-14 (AVHRR and HIRS), METEOSAT-5, METEOSAT-7, GMS-5, GOES-8 and GOES-10. BC data for April 01 for METEOSAT-5, METEOSAT-7, GMS-5 and GOES-8 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 in final testing. Delivery by ftp of all data (except DX) from the GPC to NASA Langley is underway. Delivery of D-data to ICA by ftp has been implemented; deliveries of other types of data are still being tested. The final version of the new dataset naming convention was distributed to all centers.

NOAA-14 B2 data have been received through June 01. 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). 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. Since the channel 3 switching was never implemented on NOAA-15, the cloud algorithm will not have to be changed to process these data.

NOAA-16 B2 data have been received through March 01. Processing requires the same new format and calibration procedures as for NOAA-15. Also, the cloud detection algorithm 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 has resumed and 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 February 98. These data are now being delivered. 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 97 and climatology results based on the period July 83 through December 97. The D-data document has been redone in a more convenient pdf format and separated into chapters to make downloading easier. 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 to grow gradually worse Starting in summer 00, images were deliberately truncated early (dropping the highest southern latitudes) to prevent sticking. As of July 01, the frequency of whole-Earth images has been reduced as a further preventative measure; however, the main 3-hr images required by ISCCP are still collected. GOES-M was successfully launched on 23 July 01; once check-out is complete, it will become GOES-12 and will be in stand-by mode.
