Extract GDAS 1° data
Posted: September 26th, 2018, 10:08 am
Good morning,
my name is Alessandro and I'm working on a project about volcanic fallout hazard assessment in Ecuador, where I'm using HYSPLIT to model volcanic ash dispersal and deposition. In order to produce probabilistic hazard maps, I would need to run several simulations using a statistically meaningful metereological dataset: to this purpose I have used so far meteo data from the GDAS 1°archived data (https://ready.arl.noaa.gov/ready2-bin/e ... xtracta.pl) to simulate single eruptions.
Now I would like to use the whole dataset (Dec 2004-present) to run many simulations at different times.
My question is: Is there a way to extract the whole dataset but only for a specific area?
From the above-mentioned link I know that you can do that but only week per week, while on the FTP server you can download data in a faster way but for the whole world (and it would be too big the final file).
Sorry if this is off-topic or if it has been answered elsewhere
Thanks a lot
Best Regards
Alessandro
