Re: Conversion from GRID1 to ARL

No. Instead of working with Grib, we finally decided to work with gfs0p25 meteo files at: ftp://arlftp.arlhq.noaa.gov/archives/gfs0p25

Time integrated concentration: (Bq–s/m3) or (Bq·s/m3)?

1° When used as a dispersion model of radioactive isotopes, Hysplit is issuing the exposure to the cloud in (Bq–s/m3). 2° However, I did not find any explanation in the forum on this unit, and I do not know how to use such a unit with a dose factor expressed in Sv/Bq; or in (Sv·m3/Bq·s); or in [(mSv...

It has a resolution of 2 km and weights 1.49 Go. It is limited to the ‘control’ part of the file, that is to say to 1 of the 21 fiel...
