Re: EMITIMES file

To tell HYSPLIT to use the EMITIMES.txt file you need to put the following line in the SETUP.CFG file efile='EMITIMES.txt' So you can name your emitimes file anything you want; you just need to have this line in the SETUP.CFG file. In the CONTROL file you will need to have as many sources lines as y...

Re: EMITIMES file

No problem - It's because I chose my emission duration as 5 minutes - 1/12 of an hour. The duration of the emission is specified in the 6th column in format hhmm. Then the rate of release per hour is specified in the 10th column. This is a setup I often use for testing because it's easy to look in t...

Re: EMITIMES file

Here is an example of an EMITTIMES file. This example emits 1 unit of mass over 5 minutes. 15% of the mass is emitted from 0-50m, 15% is emitted from 50-300m, and 70% is emitted from 300-1000 m. (DURATION is 0005= 5 minutes. To emit 1 unit mass total the rate is 12 unit mass/hour. 12*0.70 = 8.4 so r...

Re: Issue with GRIB data from new ECMWF data server?

We are working on a converter for the ecmwf interim dataset and will have a solution soon. There are several reasons why the current generic grib2arl does handle the ecmwf interim data well. As noted, forecast fields for the interim data set are put in a separate file from analysis fields. TPPT as w...
