Subset National Water Model (NWM) NetCDF Ver1.1

Project description

# subset_nwm_netcdf

The National Water Model (NWM) is supposed to produce forecasts in a new format (Ver1.1) starting on April 1st, 2017. Its daily output is about 400GB worth of netcdf files that contain hydrologic data/forecasts for the whole U.S. This python library enables users to subset NWM Ver1.1 NetCDFs using a polygon, which can significantly reduce data size and let researchers quickly access/store regional data they are interested in.

#Environment and Dependencies:

Preliminary functional testings passed in Python 2.7.12 x64 on Windows 7 x64 and Ubuntu 16.04 x64.

Query module:

  1. fiona @
  2. shapely @
  3. pysqlite with mod_spatialite extension @ and
  4. NWM sqlite geodatabase (4.5GB split zip files) @

Subset & Merge module

  1. NetCDF utilities (shell commands) @
  2. NCO (shell commands) @
  3. numpy @
  4. netCDF4 python lib @
  5. sed (shell command)
