<div dir="ltr">Hi all,
<div><br>
</div>
<div>I am new to using GrADS. Currently I have a script that uses the function gr2stn to pull the nearest grid point from the latitude and longitude I specify from the gridded data in a large binary file.</div>
<div>Because I want a time series, I have t set to vary, while x and y are set to 1.</div>
<div>I grab the values from the result using sublin and subwrd. I do this for each of the 4 variables that I want separately, and I have this set in a loop to get data for every day over multiple years. </div>
<div><br>
</div>
<div>This script works, but it is very slow as grabbing the daily data for 35 years takes almost a half hour!<br>
</div>
<div><br>
</div>
<div>Is there a more efficient way to pull a time series of a point from gridded data in a binary file?</div>
<div><br>
</div>
<div>Other information:<br>
</div>
<div>The gridded data is NLDAS2 forcing A which I aggregated from hourly to daily time step.</div>
<div>The daily gridded data is in a 22G binary file. </div>
<div>I am running GrADS 2.0.2 on a Mac OSX, and I call the attached script from a bash script.<br>
</div>
<div><br>
</div>
<div>Thank you for your help!</div>
