Publication State:	published
The publication state of this metadata: 'old' - for redundant records; 'working' - for new/in progress records; 'published' - for records approaching maturity, which may still change, but should be available via the discovery services; and 'Published' for mature records that are unlikely to change and should be available via the discovery services.

Summary
A brief description of the data.

Data from the CWAVE measurement campaign at the CCLRC-Chilbolton Observatory. The CWAVE campaign supported activities associated with two EC FP5 projects, CLOUDMAP2 and CLOUDNET. A wide range of satellite and ground based instruments measured a variety of atmospheric properties ranging from cloud parameters to water vapour. In addition, the measurements coincided with the results from a reduced resolution Unified Model (UM) run by the Met Office. Access to such a data set allows unprecedented comparisons between observed and modelled data.

Introduction

CWAVE is a measurement campaign at the CCLRC-Chilbolton Observatory; it is supporting activities associated with two EC FP5 projects, CLOUDMAP2 and CLOUDNET. A wide range of satellite and ground based instruments will measure a variety of atmospheric properties ranging from cloud parameters to water vapour. In addition the measurements will coincide with the results from a reduced resolution Unified Model (UM) run by the Met Office. Access to such a data set will allow unprecedented comparisons between observed and modelled data. The core observing period was 16th June to 11th July 2003.

Aims of CWAVE:

Validation and inter-comparison of cloud and water vapour measurements from satellite, with remotely sensed ground based measurements of cloud parameters and water vapour.
Comparison of measured cloud parameters and water vapour, with results from high resolution Unified Model (UM) run by the Met Office.

Restricted Data Access

These data are only available to CWAVE participants. [Apply for access].

Data availability and file format

Data are currently being submitted to the CWAVE archive.

Where ever possible the data is stored in netcdf of hdf format.

Lineage
Summary of the origins of the dataset, e.g.: "Dataset produced from NASA MODIS instrument on Terra and collected at the University of York's groundstation 1999-2003 and a copy provided to NEODC in June 2007".

Data are collected by the Chilbolton Observatory and prepared by facility staff before submission to BADC.
