Two sets of BASCOE reanalyses were produced in the framework of the GSE-PROMOTE project:
- BASCOE Analyses of UARS/MLS (1992-1999) i.e. BASCOE_MLS_v4q09
- BASCOE Analyses of Envisat/MIPAS (July 2002 - March 2004) i.e. BASCOE_MIP_v4q30
A third set of BASCOE reanalyses was produced in the framework of the MACC project:
- BASCOE Analyses of AURA/MLS (Aug 2004-Feb 2009) i.e. BASCOE_AMLS_q02.13REAb
BASCOE reanalyses BASCOE_MLS_v4q09 and BASCOE_MIP_v4q30
Daily analyses are archived as gzipped HDF-4 files.
Filenames are of the form: BASCOE_iii_version_YYYYmmddHHmm.hdf
where iii is MIP for Envisat/MIPAS and MLS for UARS/MLS, version is an identifier of the version of BASCOE used for the run, and YYYYmmddHHmm is the validity time.
The files contain the following attributes and data:
|Contact||Person of contact||character||--||--|
|BASCOE_version||Version of BASCOE, eg 'v4q30'||character||--||--|
|BASCOE_run_label||Version of BASCOE, eg 'MLS', 'MIP'||character||--||--|
|BASCOE_mode||Mode of BASCOE: 'CTM' for days without observations, else '4D-VAR'||character||--||--|
|time||Number of days since 01-Jan-2000 0UTC (MIPAS) or since 01-Jan-1991 0UTC (MLS)||float||Days||1|
|time_string||Time in the form 'dd-mmm-yyyy hh:mm:ss'||character||Days||20|
|longitude||Longitude [0 to 355]||float||Degree||72|
|latitude||Latitude [-90 to 90]||float||Degree||49|
|o3_mix||Ozone||float||Volume Mixing Ratio||72x49x37|
