Differences between results at different output resolutions and discrepancy between ascii values and corresp. contouring

Hello, We compute radioactive dispersion out various nuclear plants. In doing this we fell on some unexplained behavior 1) on the dependency of the output resolution 2) on the difference between the numerical values generated by con2asc and the isolines generated by concplot. For both aspects we ran...

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...

ascii2shp conversion software for Mac?

Hello, When working with Hysplit for Mac, it seems to me that the ascii2shp conversion software is not in hysplit/exec/ , nor accessible from the website of the Free Software Foundation. May I ask you to let me know whether it is possible––with the Mac version of Hysplit––to convert .txt into useful...

Re: Conversion from GRID1 to ARL

Many thanks for your reply. I followed your counsel. It seems to me that /data2arl/api2arl is convenient to convert GRIB2 into ARL. Conversion from GRIB1 to ARL seems to be found only when following /data2arl/era52arl. Please, let me know if I am wrong. Again, thank you very much for your help. fppi...

Conversion from GRID1 to ARL

Hi, Thank you for hysplit which is a useful tool. I would like to convert a GRIB1 file into an ARL one. The GRIB1 starts at 12.00 and ends at 12.00 the next day (24h). 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...
