<p>Hi Santiago,</p>
<p><br>
</p>
<p>rNOMADS has the ability to retrieve archived 0.5 x 0.5 degree GFS model runs, but I do not believe NOMADS has made the 0.25 x 0.25 degree archive available.
<br>
</p>
<p><br>
</p>
<p>For example, to get the archived 0.5 degree model for January 1st at 00z, do this:</p>
<p><br>
library(rNOMADS)<br>
</p>
<p>abbrev <- "gfs4"</p>
<p>model.date <- "20160101"</p>
<p>model.run <- "00"</p>
<p>pred <- "00"<br>
</p>
<p>grb.info <- ArchiveGribGrab(abbrev, model.date, model.run, pred, file.type = "grib2")</p>
<p><br>
</p>
<p>Best,</p>
<p><br>
</p>
<p>Danny<br>
</p>
<p><br>
</p>
