TRAJECTORY WEB SERVICE IS BACK ONLINE =========================================== The BADC Trajectory is now back in service at: BADC Support 26/06/03.

TRAJECTORY WEB SERVICE TEMPORARILY UNAVAILABLE =================================================== We regret that the BADC trajectory service is not currently available due to a technical problem. We hope to have it fixed shortly. Sorry for any inconvenience. BADC Support 20/06/03.

A new batch of high resolution radiosonde data is now available from the BADC. ============================================================================== The dataset now includes more recent data and data from extra stations. In particular 3 years of data from the St Helena site, and data from the new Met Office autosonde sites is now available. More information about the High Resolution data held at the BADC can be found at: BADC Support 03th June 2003

Earth Probe TOMS went into safehold mode at 0025UTC on May 15, 2003. The problem appears to be a single event upset (SEU) in the attitude control system. This is very similar to the event that occurred in August 2002. TOMS is hoped to be back in science mode operation within a week. ...

The Met Office has now stopped updating GISST/GIICE datasets. HadISST 1.1 is the replacement product provided by the Hadley Centre at the The Met Office. It contains monthly long-term global gridded SST and sea ice analysis (1870 to present). This dataset was available from the Met Office as an historical dataset and is now being made operational (i.e. updated every month). HadISST has a different sea-ice analysis from GISST; as a consequence of this, the data will not be available until the 2nd of the month, 2 months afterwards (e.g. January's data will become available in March). To find out more about this new dataset and access restrictions, please read through the [HadIsst dataset web pages](/data/hadisst/). BADC Support 16/04/03.

The Met Office had planned to stop updating GISST/GIICE datasets in May 2003. However, some problems were encountered in producing the GISST updates from March 2003. "The current route for producing GISST uses the version 1 of the Reynolds optimally interpolated SSTs as background field in some areas, and these fields are no longer being produced. We (The Met Office) could switch to using version 2, but this would produce some differences in the result, particularly for areas close to sea-ice." After careful consideration, the Met Office has decided to stop updating the GISST/GICE datasets. The last update is therefore for February 2003. The Met Office has a replacement product, called HadISST, which has been available from the Met Office as an historical dataset and is now being made operational (i.e. updated every month). HadISST has a different sea-ice analysis from GISST; as a consequence of this, the data will not be available until the 2nd of the month, 2 months afterwards (e.g. January's data will become available in March). The BADC is now working on making this replacement dataset available to registered users. Users will be informed in due course. We are sorry for the inconvenience this may cause in the meantime.

Temporary Disruption to BADC FTP service on Friday 11th April 2003 from 2pm ============================================================================ The power supply to selected BADC computers is being checked. This will result in the disruption of BADC FTP services from 2pm on Friday 11th April for about an hour. Data will still be available for [download via the web](http://badc.nerc.ac.uk/cgi-bin/data_browser/data_browser). We are sorry for the inconvenience this may cause. BADC Support 10/04/03.

The BADC have opened a public discussion forum for discussion of anything related to atmospheric science or the data held by the BADC. You don’t even have to be registered to contribute! ...

The technical problems affecting the BADC over the past two day ( see previous news item) have now been fixed and all areas of the BADC site are now operational. We appologise for any inconvenience this disruption may have caused. ...
