Features#

Data aggregation tool#

Data selection, resolution transformations, and aggregation functions for gridded datasets.

Workflow:

  1. Data selection: Select data that will be included in the analysis (times of interest and spatial areas of interest)

  • Time selection: Time ranges or conditional time selection (e.g. winter only, certain years only)

  • Spatial selection: Select data within polygon boundaries, or mask data outside polygon boundaries

  1. Resolution and re-gridding

  • Thin

  • Coarsen

  • Interpolate

  • Re-grid to align with another dataset

  1. Group selection

  • Time selection

  • Zonal statistics

  1. Aggregation

  • Mean, standard deviation, counts

  • Counts exceeding threshold

  • First day threshold exceeded

Utilities#

  • Subsetting tool: Efficiently create subsets from very large geographic datasets, and visualize the results

  • Convenience functions for getting information (e.g. metadata, number of records, coordinate system, spatial extent) from a large dataset without reading the dataset into memory

  • File conversions

    • convert .grib files to netcdf files

    • convert a stack of geotiff files to a single netcdf
