This file contains background information to help you get the HALOE L3 data held at the BADC.
All data is located beneath the directory /badc/haloe/. Here you will find a README file and the following subdirectories:
Check whether the data you require is available by browsing the HALOE L3 data directories.
The data files (*PROD extension) are in subdirectories 3at/subtype/yyyy/mm, where subtype corresponds to a measured parameter (aextch4, aexthcl, aexthf, aextno, ch4, h2o, hcl, hf, no, no2, o3, or temp), yyyy is the year, and mm is the month of the data. Each data file has an ASCII file (*META extension) associated with it, which contain information about the data file.
The 3tp subdirectory (in the haloel3 data directory)contains the parameter files which are associated with each data file. There are two parameter files per day. The first, 'lat' gives the latitudes for each profile level, and 'lon' gives the longitude for each profile level. The data files only contain the average latitude and longitude for the profile. The parameter files also have corresponding ASCII metadata files.
Software is also available to read the data (as provided by Goddard DAAC User Support Office).
