Overview
This library is basically a wrapper around the UniData NetCDF Java library with some additional abstractions to make it integrate better with Clojure. Documentation for the Java library, plus tutorials and other information can be found at the UniData Java Library Home Page .
Unlike the base Java library, this library makes no attempt (at this time) to provide functionality for the creation of NetCDF files. The focus of this library is the exploration and extraction of data from NetCDF files.
This library is broken up into a number of modules
- attributes: Functions dealing with variable attribute information
- dimensions: Functions dealing with variable dimension information
- groups: Functions dealing with NetCDF groups
- netcdf4: Low level NetCDF file operations
- ranges: Functions dealing with ranges of data in NetCDF variables
- variables: Functions to manipulate NetCDF variables
The library attempts to provide high level functions which are useful for exploring NetCDF files such as determining the number and structure of groups, variables and dimensions etc. The library also provides functions to extract individual data elements, slices of data variables or whole grids of data.
One aim of this library is to make the processing of data from NetCDF files reasonably efficient. This library is currently being used to extract weather records for processing and insertion into a Postgres database. A secondary use of this library is for the exploration of NetCDF data files containing weather data and help identify the source of anomalies and errors in various predictive models that use the data from these files.
Modules
clj-netcdf.netcdf4
This is a low level module which provides basic NetCDF file processing functions.
