[gradsusr] Generating weather charts...please help me

[Jayson Escalante]

To whom it may concern:

I would like to automatically generate weather charts at set times
using the Global Spectral Model of the Japan Meteorological Agency
using GrADS (Grid Analysis and Data System, http://opengrads.org/).
Right now, I just download GRIB files one by one, generate the CTL and
index file, and run the scripts on GrADS by myself.

I chose JMA-GSM (instead of meteorology heavyweights GFS and ECMWF),
as there are only a few websites offering graphics for this forecast
model. Furthermore, I noticed their precipitation forecasts for the
Philippines were more accurate compared to that of the GFS (used by
The Weather Network) and Windy (used by Windy app)

I intend to create charts for two areas:
(1) Western Pacific region (95E ~ 170E, Equator ~ 45N); and,
(2) the Philippines (4N ~ 22N, 110E ~ 135E)

The weather charts I intend to create for each of those regions include:
(1) Mean Sea Level Pressure
(2) Six-Hourly Precipitation Rate
(3) Surface Wind Direction and Speed
(4) Significant Wave Height
(5) Geopotential Height, and Wind Speed/Direction for 925, 850, 700,
500, 300, and 200 hPa

The raw files for the model will be downloaded from either
(http://apps.diasjp.net/gpv/cgi-bin/GPVlist3.sh) or
(
https://www.wis-jma.go.jp/d/o/RJTD/GRIB/Global_Spectral_Model/Latitude_Longitude/1.25_1.25/90.0_-90.0_0.0_358.75/Upper_air_layers/
)

JMA-GSM data are updated four times a day, but I aim to use two runs
only: 00:00 and 12:00 UTC.

The charts will be uploaded on my weather hobby website
(www.jqweather.com). I don't intend to generate charts as fancy as
those used in Windy or Ventusky; all I want are single images (i.e.
one image for the 3rd hour forecast, another for the 6th hour
forecast, another for the 12th hour forecast, etc) that could be
easily accessed even by people back in the Philippines who have slow
internet connections.

I am on a meager budget, and I would greatly appreciate any help to
make this project possible. Aside from writing scripts on GrADS (which
I used to generate the charts at home), I have zero experience in
programming and other complex computer stuff.

Again, Any help to make this dream of mine a reality is greatly
appreciated. Thank you very much!


Yours sincerely,
Jayson Quinones
