📄 Filename Structure
Files follow this naming pattern:
PIKART_<version>_<catalog>_<source>_<spatial>_<temporal>_<year>.nc
- version: version of the catalog
- catalog:
eulerian or lagrangian catalog version
- source:
ERA5 or MERRA2 reanalysis data
- spatial: grid resolution (e.g.,
0p5deg = 0.5°)
- temporal: time resolution (e.g.,
6hr)
- year: calendar year (e.g.,
2023)
- .nc: NetCDF file format
Examples
PIKART_V1.0_lagrangian_ERA5_0p5deg_6hr_1940.nc →
Lagrangian trajectories from ERA5, 0.5° grid, 6-hourly, year 1940, from catalog version 1.0.
PIKART_V1.1_eulerian_MERRA2_0p5deg_0p625deg_3hr_2020.nc →
Eulerian data from MERRA2, 0.5° × 0.625° grid, 3-hourly, year 2020, from catalog version 1.1.
Important note
Please access the data using Python, MATLAB, or any other analysis software (e.g., as suggested by the examples). Direct download from the web page is not recommended, as it can cause high server load, may produce errors, does not allow reproducible data retrieval, and does not allow fine-grained data access.
