NUMBER 305 DATE: 09/04/09

Sector Processing Center (SPC):

During April, NOA (100%) and EUM (100%) processed A data into B1/B2 data. During May, NOAA (100%, EUM (100%) and JMA (100%) processed A data into B1/B2 data. During June, NOA (100%), CSU (99.2%) and JMA (100%) processed A data into B1/B2 data. During July, NOA (100%), EUM (100%) and JMA (100%) processed A data into B1/B2 data.

Normal operations for May, June and July were reported by NOA, EUM and JMA.

Brazil (INPE) has delivered test B1 data from GOES-10 in the B1U format, which are acceptable for processing, so deliveries of complete B1 data will commence soon. It was decided to forgo delivery of B2 as the beginning of processing using B1U is very near; GOES-10 data will be incorporated into the new ISCCP products next year.

Satellite Calibration Center (SCC):

AC data were received for May, June and July 09 from MTSAT-1R, FY-2C, METEOSAT-7, METEOSAT-9, GOES-11, GOES-12 (AC data is being supplied by CSU for both GOES satellites) and NOAA-18. BC data are complete through May 09 for MTSAT-1R, FY-2C, METEOSAT-7, METEOSAT-9, GOES-11 and GOES-12.

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 for METEOSAT-7 and GOES-12 which do not have a split-window channel).

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. Production of NOAA-18 (preliminary) B3 is complete through June 08. Final B3 data have been produced through June 08.

Deliveries of B2 data from NOAA-17 are current. Production of NOAA-17 (preliminary) B3 is complete through June 08. Final B3 data have been produced through June 08.

Deliveries of B2 data from GOES-11 are current. Production of GOES-11 (preliminary) B3 is complete through June 08. Final B3 data have been produced through June 08.

Deliveries of B2 data from GOES-12 are current. Production of GOES-12 (preliminary) B3 is complete through June 08. Final B3 data have been produced through June 08.

Deliveries of B2 data from METEOSAT-7 (at 55E) are current. Production of METEOSAT-7 (preliminary) B3 data is complete through June 08. Final B3 data have been produced through June 08.

Deliveries of B2 data from METEOSAT-9 are current. Production of METEOSAT-9 (preliminary) B3 data is complete through June 08. Final B3 data have been produced through June 08.

Deliveries of B2 data from MTSAT-1R are current. Production of MTSAT-1R (preliminary) B3 is complete through June 08. Final B3 data have been produced through June 08.

Delivery of B2 data from FY-2C are current. Processing of these data has commenced but some irregularities in the format of the earliest datasets are still being investigated.

Deliveries of TOVS correlative data are current. TOVS processing is complete through June 08.

Deliveries of snow/ice correlative data are current. SI processing is complete through June 08.

DX/D1/D2 data processing is now complete through June 08 (without FY-2C). First tests of the smaller-scale spatial contrast test shows that it does not add any significant improvement because other parts of the algorithm had already detected the additional clouds. Further tests will be conducted to refine the detection thresholds and to add another spectral contrast test to improve polar cloud detections.

The online bibliography of papers based on ISCCP datasets has been updated through December 06; over 1300 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 08.

ISCCP Central Archives (ICA):

The ICA at NOAA NCDC continued to receive B1 data from NOA, JMA, EUM, CSU, MSC and CMA and B3 and DX/D1/D2 data from the GPC in a routine manner.

The health of GOES-10, GOES-11, MTSAT-1R, METEOSAT-7, METEOSAT-9, FY-2C, NOAA-17 and NOAA-18 remained good. METEOSAT-5, METEOSAT-6, METEOSAT-8, GOES-13, MTSAT-2 and NOAA-19 are in stand-by mode. METEOSAT-9 again entered safe mode on 15 August and was temporarily replaced by METEOSAT-8.
