CLARE98 data overview

These pages were copied from the original CLARE'98 FTP site, with no changes except the addition of this comment. You can download the entire dataset here: clare98.tar.gz (718 MB). Some of the named contacts have retired or moved to other institutes, so if you have any queries on the data then in the first instance you should contact Robin Hogan.

Guidelines for puplications using CLARE'98 data

If you use the published data from a particular aircraft or instrument (not your own) then contact the person responsible for the specific data regarding co-authorship. If no co-authorship is requested then in put in the acknowledgements words to the effect:

The [whatever (lidar/FSSP/radar etc.)] data was provided by [Name/Acronym of institution (reference)] and processed by [Name of investigator or whoever did the processing].

In the references include the appropriate paper from the CLARE'98 proceedings that refers to the instrument(s)/aircraft(s).

It goes without saying that if a scientist from another institution has to help our with the data by, for example, processing or re-processing the data, then co-authorship should be offered.

In the acknowledgements include a sentence to the effect:

The data used in this work/report/paper was collected during the CLARE'98 campaign carried out under the auspices of the European Space Agency (Ref. to workshop proceedings).

DOCUMENTS

  • Papers for the CLARE98 Final Workshop at ESTEC, 13-14 September 1999.

UKMO model (U. OF READING - ROBIN HOGAN)

  • Time series of T, P, Wind (include vertical), humidity, cloud fraction and water content .
  • Data available interpolated on to the Chilbolton location and the 50 km flight track to the west.
  • Only the seven flight days are available.
  • Grid box is of size about 12.5 km, 35 levels (approx 10 Mbytes).
  • Includes attenuation parameters at 35 and 94 GHz.

ECMWF model (U. OF READING - ROBIN HOGAN)

  • Time series of T, P, Wind (include vertical), humidity, cloud fraction and water content.
  • Every hour for the whole project, over Chilbolton only.
  • Grid box is of size about 50 km, 31 levels (approx 7 Mbytes unzipped).

Comparison of aircraft tracks for the coincident runs

  • Need to know how coincident they are in the horizontal.
  • Directory includes aircraft vertical soundings and Larkhill radiosonde ascents.

CO-ORDINATED BY CETP - JACQUES TESTUD.
