Detailed Description

Query NCDC archive for climate data for all stations in the Global Historical Climatology Network (http://www1.ncdc.noaa.gov/pub/data/ghcn/daily/readme.txt) that fall within a bounding box.

Will find all stations within the study area bounding box. Requires that the GHCN station database be setup using GHCNDSetup.py. Database must be stored in a location specified by a configuration file containing the section 'GHCND', and value 'PATH_OF_STATION_DB'.

Pre conditions

1. Configuration file must define the following sections and values: 'GHCND', 'PATH_OF_STATION_DB'
2. The following metadata entry(ies) must be present in the study area section of the metadata associated with the project directory: bbox_wgs84

Post conditions

1. Will write ClimatePointStation entries to the climate point section of metadata associated with the project directory:
2. Will save climate data files to outdir

Usage:

GetGHCNDailyClimateDataForStationsInBoundingbox.py -p /path/to/project_dir

Note

EcohydroLib configuration file must be specified by environmental variable 'ECOHYDROWORKFLOW_CFG', or -i option must be specified.

Todo:

parse data files to determine start date, start time, and variables
