Please see my previous post for an introduction to ERDDAP.
ERDDAP is Cloud based data broker designed to act as the intermediary between developers/users and scientific data formats (particularly gridded data). Fortunately the GFS forecast is also available on an ERDDAP server. However if you navigate to the above link you will be confronted with data files in some difficult to use scientific formats such as GRIB (Gridded Binary). The forecast data is released under an OpenData licence and is accessible directly at the following address GFS is a global numerical weather prediction system that is run 4 times a day on a powerful super computer. We are going to use weather forecast data from the Global Forecast System (GFS) of the USA’s National Weather Service (NWS).
You only need this if you don’t already have some data describing coastlines, countries etc. This is a collection of public domain map data that describe the planet, ( ). The Natural Earth Quick Start data set.I will be using MS Excel but I have also tried this with Softmaker Office and I am sure LibreOffice (free software) will work or indeed any other spreadsheet application I am going to use QGIS (free software) but I have done this with ESRI ArcMap as well In this post we are going to look at how to get weather forecast data and display it as a layer in a desktop geographical information system (GIS).
