Re: "Missing data" file boundary problem with CFS/GFS
According to chk_file, the missing fields are the first two levels of the last time period of each file: ... 3706 10 516 0 6 099MSLP 2 0.1574803E-01 0.1013963E+04 3707 10 516 0-1 199HGTS 0 0.0000000E+00 0.0000000E+00 3708 10 516 0-1 199TEMP 0 0.0000000E+00 0.0000000E+00 3709 10 516 0-1 199UWND 0 0.0...

Re: how to use EC-EARTH data in HYSPLIT?
I imagine that the levels are something like 850 hPa, 700 hPa, 500 hPa? You can certainly interpolate this vertically, but again it will not be very accurate because there should be lots of directional shear between those heights. I would recommend using isobaric trajectories and initializing them a...

"Missing data" file boundary problem with CFS/GFS
I've encountered a problem with missing data warnings in converted 0.5deg CFS output. I used grib2arl since the output is on the same grid as some versions of GFS, and modified CFG_GRIB to match the necessary variables. Once I've converted multiple files, I can run both the trajectory and dispersion...

Re: Compile issues on CentOS 5.8
I've previously encountered issues using some hysplit programs with recent netcdf libraries (>4.1). Installing netcdf 3.6.3 in addition to 4.2, and linking to that in the Makefiles, may solve your problems. Also, as mentioned above some versions of netcdf build the fortran and c libraries separately...

Re: how to use EC-EARTH data in HYSPLIT?
What is the vertical coordinate? If the winds are on isobaric surfaces, you could at least compute isobaric trajectories. I fear that 3 levels would be too few to perform reasonable interpolation of vertical motion, though. You might be able to modify arw2arl.f to do the necessary conversion (it wor...

Re: Adding non-advection meteo variables
A follow-up question on this topic: is it possible to output interpolated meteorological variables on the concentration grid, similar to the way it is done for trajectories? I realize that this might not seem that useful, but it would be very handy for situations where one wants to evaluate the surf...

Re: Adding non-advection meteo variables
Thanks for the help! In case anyone else feels compelled to do the same, to get access to the fields I only needed to modify: library/hysplit/DEFARG2.INC (interfaces to metinp and advmet) library/hysplit/DEFMETO.INC (METO sequence definition) library/hysplit/advmet.f (returns local meteorology at a ...

Re: NCEP Climate Forecast System Reanalysis for HYSPLIT?
I'm not sure if you're still working on getting CFSR working with HYSPLIT, but I recently modified gfs2arl to read and convert the 0.5-degree CFSR files to ARL format. Let me know if you're interested, and I can send it to you. Similarly, I'd be interested to hear about your experience using CFSR if...

Adding non-advection meteo variables
I'm trying to add some surface fields for use in the deposition model, and am wondering about the easiest way to do it. I have successfully modified gfs2arl to add the necessary fields to the ARL-format binary met files, and have added flags to DEFMETO.INC and metini.f (these confirm that Hysplit ca...
