Draw Your Own Customized Plots
Here's how to re-create and customize some of the images you've seen on this web site. In all cases, the software is freely available, and the data are accessible on the GDS. The first thing you must do is install GrADS on your local computer. Additional instructions are organized below according to the type of plot you want to draw.

Forecast Meteograms

To display forecast meteograms, copy the following files into your working directory:

meteogram_gfs.gs GrADS script displays a 0-180hr forecast meteogram for a given location.
meteogram_gfsb.gs GrADS script displays a 8-16day forecast meteogram for a given location.
   

Make sure you're using the DODS-enabled GrADS executable, gradsdods, and then run the script. The script will prompt you for the required arguments, or you can provide them on the command line. Usage examples and other relevant information about the meteogram script are contained in the script header.

Subdivisional Rainfall

To display subdivisional rainfall values (climatologies, total rainfall, or % difference from normal), copy the following files into your working directory:

Required Supplemetal Files:
india_polygons.asc ASCII file contains the coordinates of the subdivisional boundaries.
readpolygons.gsf GrADS script function called by the display scripts.
indiaregions

Put this GrADS map file in the directory where the other GrADS font and map files are located on your system.

GrADS Display Scripts:
subdiv_clim.gs Draws a spatial map of monthly, seasonal, or annual climatological rainfall totals for subdivisions of India.
subdiv_pdn.gs Draws a spatial map of monthly, seasonal, or annual rainfall % departures from normal for subdivisions of India.
subdiv_total.gs Draws a spatial map of monthly, seasonal, or annual rainfall totals for subdivisions of India.
subdiv_timeseries.gs Plots a variety of rainfall timeseries for each subdivision of India (no supplemental files required).
   

Make sure you're using the DODS-enabled GrADS executable, gradsdods, and then run the display script. Each script will prompt you for the required arguments, or you can provide them on the command line. More detailed instructions are contained in the first few lines of each script.
