How do I open a grib2 file?
You need a suitable software like ArcGIS from ESRI to open a GRB2 file. Without proper software you will receive a Windows message “How do you want to open this file?” or “Windows cannot open this file” or a similar Mac/iPhone/Android alert.
What is a grib2 file?
GRIB is a file format for the storage and transport of gridded meteorological data, such as Numerical Weather Prediction model output. It is designed to be self-describing, compact and portable across computer architectures. The GRIB standard was designed and is maintained by the World Meteorological Organization.
What is GRB file?
Meteorological data file created in the GRIdded Binary format; may contain both historical and forecasted weather data; can specify temperature, humidity, precipitation, and hundreds of other factors; used for interchanging weather data between software systems.
How to extract specific information from GRIB2 file?
So far, I tried to download original GRIB2 file from www.ftp.ncep.noaa.gov and run few Python API example scripts from mentioned ECMWF Wiki page. Since Python API documentation doesn’t exist, I have some hard time to understand which methods should I use in order to:
How to download Grib GFS files with specific filters?
This could be half-solved with filtering the data I need before downloading the file (results in much smaller file) but I’m still not sure how to do it (part of Downloading GRIB GFS files with specific filters? ), but still I’d like to figure this out since it might happen that I will occasionally have to download “full” files.
Is there a problem with the GRIB code?
The problem with this code is that it iterates trough the whole file, all the messages and all possible coordinates (whole planet, 0.25 degrees precision). If file is 300+ MB it takes a while to read it.
How big is a global GRIB2 grid file?
It’s easy to use and works well and with good performance for worldwide GRIB2 files with 0.125×0.125 degrees grid, which are about 8 MB in size. Thanks for contributing an answer to Geographic Information Systems Stack Exchange!
