Format Requirements for Weather Datasets
ModelArts Studio supports the import of weather datasets, including marine meteorological data.
Marine meteorological data is usually derived from weather reanalysis. Weather reanalysis uses modern weather models and data assimilation technologies to reprocess historical observation data and generate high-quality weather records. The data can be global or region-specific, aiming to provide complete, consistent, and high-resolution weather data.
The reanalysis data is in binary format. For details about the format requirements, see Table 1.

Meteorology - Weather data |
nc, cdf, netcdf, gr, gr1, grb, grib, grb1, grib1, gr2, grb2, and grib2 |
Weather data usually includes global or regional weather variables, such as temperature (T), atmospheric pressure (P), and wind speed (U and V). In a file, these variables may be arranged by time, geographical range, and pressure level. The following is an example: {"geo_range": {"lat": ["-90.0", "90.0"], "lon": ["0.0", "360.0"]}, "time_range": ["1640995200000", "1641164400000"], "total_size": 7376211808, "surface_features": ["P", "T", "U", "V"], "upper_air_layers": ["1000hPa", "100hPa", "150hPa", "175hPa", "200hPa", "250hPa", "300hPa", "400hPa", "500hPa", "50hPa", "600hPa", "700hPa", "850hPa", "925hPa"], "upper_air_features": ["Q", "T", "U", "V", "Z"]}

Meteorology - Ocean data |
nc, cdf, netcdf, gr, gr1, grb, grib, grb1, grib1, gr2, grb2, and grib2 |
|
Meteorology - Ecological data |
nc, cdf, netcdf, gr, gr1, grb, grib, grb1, grib1, gr2, grb2, and grib2 |
Ecological data usually includes ecological variables such as total chlorophyll concentration (Tca), chlorophyll concentration (Chl), and diatom concentration (Dia). The following is an example: {"geo_range": {"lat": ["-90.0", "90.0"], "lon": ["0.0", "360.0"]}, "time_range": ["1640995200000", "1641164400000"], "total_size": 7376211808, "surface_features": ["Tca","Chl","Dia","Coc","Cya","Irn","Nit","MLD"]}
|
Meteorology - Wave data |
nc, cdf, netcdf, gr, gr1, grb, grib, grb1, grib1, gr2, grb2, and grib2 |
Wave data usually includes the significant wave height (SWH). The following is an example: {"geo_range": {"lat": ["-90.0", "90.0"], "lon": ["0.0", "360.0"]}, "time_range": ["1640995200000", "1641164400000"], "total_size": 7376211808, "surface_features": ["SWH"]}
