Met Office Stratospheric Data - - NESDIS made a change to NOAA-16 processing affecting the stratospheric data ============================================================ Message from the Met Office: "NESDIS made a change to NOAA-16 processing on 22/11/02, which they expected to be null but has actually caused a significant degradation. As a result it has been excluded from the observations since then. This has significantly effected the stratospheric data. Efforts are being made to rectify this problem and we hope to be able to carry out reruns within a few weeks. Sorry for the inconvenience. In addition to the NOAA-16 problems we have realised that we have been failing to use NOAA-17 observations, which is why the impact of NOAA-16 failing was so severe. We hope to begin using the NOAA-17 observations operationally today, and reruns should follow." BADC Support 27th November 2002

Haloe Level 2 version 19 data now updated to 21 October 2002 ============================================================ More information about this dataset is available at BADC Support 20/11/02.

Telnet connections to the BADC file server not supported from January 2003 ========================================================================== As of January 2003, connections to tornado, the BADC file server, through Telnet and rlogin will not be supported. However, connections through SSH are supported. SSH stands for Secure Shell, a program to log into another computer over a network, to execute commands in a remote machine. SSH is a program very similar to Telnet.The difference is that SSH uses encryption to keep the connection secure so that it is more difficult for hackers to spy on users password or other sensitive information that may pass through the connection. If you have an account on tornado, then you need to download and install an SSH client program onto your computer. For more details including links to SSH downloads, please go to the [Help page](/help/software/ssh/)

Met Office Stratospheric Data - now using OPERH identifiers ============================================================ The Middle Atmosphere Group at the Met Office has changed the data assimilation model to include a bug fix that corrects a persistent singularity over the South Pole in the stratosphere. It is only a minor change, but as of yesterday's (26 Feb 2002) 12Z run, the assimilation identifier has been changed from OPERG to OPERH (e.g. ppassm_operh_y02_m02_d26_h12.pp ) If you require any more details on this change, please contact the BADC in a first instance. Thank You. BADC Support 27th February 2002
