IAGOS-CARIBIC whole air sampler data (v2025.07.11)

Content

IAGOS-CARIBIC_WSM_files_collection_20250711 contains merged IAGOS-CARIBIC whole air sampler data (CARIBIC-1 and CARIBIC-2; <https://www.caribic-atmospheric.com/>). There is one netCDF file per IAGOS-CARIBIC flight. Files were generated from NASA Ames 1001 source files. For detailed content information, see global and variable attributes. Global attribute `na_file_header_[x]` contains the original NASA Ames file header as an array of strings, with [x] being one of the source files.

Data Coverage

The data set covers 22 years of CARIBIC data from 1997 to 2020, flight numbers 8 to 591. There is no data available after 2020. Also, note that data isn't available for all flight numbers within the [1, 591] range.

• CARIBIC-1: flight no. 8 to 97
• CARIBIC-2: flight no. 127 to 591

Special note on CARIBIC-1 data

CARIBIC-1 data only contains a subset of the variables found in CARIBIC-2 data files. To distinguish those two campaigns, use the global attribute 'mission'.

File format

netCDF v4, created with xarray, <https://docs.xarray.dev/en/stable/>. Compression: zlib, level 5. Metadata conventions: CF-1.10, ACDD-1.3 (see also 'comment'  global attribute).

Data availability

This dataset is also available via the KIT-IMKASF THREDDS server, <https://thredds.atmohub.kit.edu/thredds/catalog/iagos-caribic/catalog.html>.
