grib2geotiff - Gribfile to Geotiff

This handy tool converts Gribfiles to Geotiffs. Gribfiles (.grb, .grib or .grib2) are the de-facto standard file format in the Meteorology world while Geotiff (.tif) has the same rank in the GIS world. Because Gribfiles are binary with a lot of free configuration capabilities, not every GIS tool can handle these files properly.

Usage

A Gribfile can contain hundreds of records, while one record usually represents one specific meteorological parameter with a rich set of metadata. grib2geotiff converts all records of a Gribfile to atomized Geotiffs. The converted Geotiffs are grouped by the parameter's metadata so that the bulk of them is manageable. The important parameter's metadata like level, unit or reference and forecast time is applied to the Geotiffs metadata.

Install

To install this tool you need to install Git, Maven and Java 8 first.

1. clone this repository via Git: git clone https://github.com/MeteoGroup/grib2geotiff.git
2. go into the directory: cd grib2geotiff
3. build the java sources with Maven: mvn package

Run

java -jar target/grib2geotiff.jar -in [inputDirectory] -out [outputDirectory]

• inputDirectory should contain one or more Gribfiles form the Global Forecast System (GFS), which can be downloaded from their FTP server: ftp://ftp.ncep.noaa.gov/pub/data/nccf/com/gfs/prod/ .
• outputDirectory will contain all Geotiffs in the file structure schema below. This folder will get created if it does not exist.

[outputDirectory]/
└── [referenceTime]/
    └── [category]/
        └── [parameterName]/
            └── [parameterName]_[level]_[forecastTime].tif

• referenceTime is the time the whole forecast is referenced to
• category is the parameter's category
• parameterName is the name of the parameter
• level is the elevation (if set), often in meters (m) or hectopascal (hPa)
• forecastTime is the time when the forecast affects

Limitations

GFS only

Currently this tool is only tested with Gribfiles from the GFS. But feel free to try Gribfiles from other data sources.

mixed resolutions

Currently grib2geotiff is overwriting already existing Geotiffs. So the processing the Gribfiles with the same referenceTime und forecastTime but different resolutions has to be done in two steps. See this two Gribfiles:

• gfs.t18z.pgrb2.1p00.f003
• gfs.t18z.pgrb2.2p50.f003

Example

1. The GFS Gribfile gfs.t18z.pgrb2.1p00.f003 was downloaded from the GFS FTP server and placed in the folder /geodata/weather/input/
2. The tool is executed with the command java -jar -in /geodata/weather/input/ -out /geodata/weather/output/
3. The output folder now contains XXX Geotiffs where each of them represents one record / parameter of the given Gribfile (see list below)
