Introduction

Data were collected from the 4th of April 2002 to the present by the Ultra-violet Raman lidar at Chilbolton Observatory, Hampshire.

The dataset contains measurement and display of the full Doppler spectrum, and the moments Z, v and w of air.


Restricted Data Access
Chilbolton dataset access conditions provide information as to who may use the data and how it can be accessed.

Data availability and file format

CAESAR data are stored in either NetCDF or NASA Ames format.


Further information about the CAESAR project can be found on the Science and Technology Facilities Council (STFC) CAESAR webpage, the Met Office CAESAR webpage, and the Facility for Airborne Atmospheric Measurements CAESAR webpage.

The STFC have a webpage which describes how and what data are collected by the clear air ACROBAT radar.


Who to contact

If you have queries about these pages or about obtaining the data from the BADC then you should contact CEDA Support. Your query should be answered within one working day. When follow-up work is required, the CEDA support will carry out the work as quickly and efficiently as possible, and in any case, the user will be kept informed of progress.
