ISCCP PROJECT STATUS REPORT
NUMBER 276 DATE: 7/13/06
CENTER ACTIVITIES
Sector Processing Center (SPC):
During May, NOA, EUM, MSC, CSU and JMA processed greater than 99% of A data into B1/B2 data. CSU processed more than 99% of A data into B1/B2 data for January, February, March and April..
Normal operations for May were reported by NOA, EUM, MSC, CSU and. JMA.
Satellite Calibration Center (SCC):
AC data were received for May 06 from MTSAT-1R, FY-2C, METEOSAT-5 and METEOSAT-7. Also AC data for April and May 06 were received for NOAA-18 (AVHRR and HIRS). BC data for January, February and March 06 for MTSAT-1R, for February and March 06 for FY-2C, GOES-10 and GOES-12, and for February 06 for METEOSAT-5 and METEOSAT-7 were shipped to the GPC.
Apparently, the HIRS data from NOAA-18 has a lot bad data causing loss of the normalization of the “water vapor” channels for some months.
Work continues to accommodate the AC data for MSG (METEOSAT-8).
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 and GOES-12 which do 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 from the GPC are delivered by ftp to NOAA/NCDC and to NASA Langley.
Deliveries of B2 data from NOAA-18 are current.
Deliveries of B2 data from NOAA-17 are current. Production of NOAA-17 (preliminary) B3 is complete through December 05. Final B3 data have been produced through December 05.
Deliveries of B2 from GOES-9 (at 155°E) are complete through October 05, the last data. Production of GOES-9 (preliminary) B3 is complete through June 05. Final B3 data have been produced through June 05.
Deliveries of B2 data from GOES-10 are complete through June 06, the last data. Production of GOES-10 (preliminary) B3 data is complete through June 05. Final B3 data have been produced through June 05.
Deliveries of B2 data from GOES-12 are current. Production of GOES-12 (preliminary) B3 data is complete through June 05. Final B3 data have been produced through June 05.
Deliveries of B2 data from METEOSAT-5 (at 63°E) are current. Production of METEOSAT-5 (preliminary) B3 data is complete through June 05. Final B3 data have been produced through June 05.
Deliveries of B2 data from METEOSAT-7 are current. Production of METEOSAT-7 (preliminary) B3 data is compete through June 05. Final B3 data have been produced through June 05.
Deliveries of B2 data from MTSAT-1R are current.
Deliveries of B2 data from FY-2C have been made for August through October 05. Delivery of FY-2C data via Internet has encountered problems that appear to be caused by a too-slow connection with China; this is being investigated. The formatter software for FY-2C is finished but the navigation subroutine is still being tested.
Deliveries of TOVS correlative data are current. TOVS processing is complete through June 05.
Deliveries of snow/ice correlative data are current. IS processing is complete through June 05.
DX/D1/D2 data processing is complete through June 05. Production of D data will be suspended until the end of this year to accumulate sufficient NOAA-18 data to re-establish the radiance calibration. The opportunity will also be exploited to link the ISCCP calibration to that for MODIS and to compare results with independent analyses for AVHRR and METEOSAT by NOAA and EUMETSAT, respectively.
The online bibliography of papers based on ISCCP datasets has been updated through December 04; over 1000 ISCCP-related papers have been published.
The cloud climatology plots and browse data, the BT and D2 holdings on the ftp site, the radiance calibration and product version number tables have all been updated through June 05.

A new set of pages has been set up on the GEWEX Radiation Panel web site at http://grp.giss.nasa.gov to provide an overview of the comparisons among about half a dozen global cloud datasets. Investigation of these datasets over the next year or so will provide an evaluation of their accuracy.
ISCCP Central Archive (ICA):
The ICA at NOAA NCDC continued to receive B1 data from NOA, MSC, EUM, CSU and JMA and B3 and D data from the GPC in a routine manner. A new effort is underway to bring the documentation, formats and READ software for the B1 datasets up to the same level as for the B3 datasets. A prototype version of these data, to be called B1U, is now being examined to test their accuracy and usefulness. NCDC has now put the entire DX dataset online.
SATELLITE HEALTH
The health of GOES-10, GOES-12, MTSAT-1R, METEOSAT-5, METEOSAT-7, FY-2C, NOAA-17 and NOAA-18 remained good. METEOSAT-8 is also operating routinely; METEOSAT-9 is undergoing commissioning and will become operational in August 06. METEOSAT-6 is in stand-by mode. GOES-11 replaced GOES-10 at the West position on 27 June 06. GOES-10 is going to be moved to 60 degrees west and be operated by Brazil. GOES-13 was successfully launched on 25 May 06 and is undergoing commissioing. METOP-1 launch is scheduled for mid-06. CloudSat and Calipso operations have begun.
