Trajectory Source Geolocation

Hi, I am currently utilizing the trajectory source geolocation script with my own sampling data. The estimate for the source location (red grid cell) seems to be at the location of the sampling site and does not converge to the source location. The contours are also very trajectory like, they are na...

Source Term Geometry

Hi, I am aware that HYSPLIT can do a stack emission release by doing multiple releases at different heights with the same longitude and latitude. Are they any more capabilities where HYSPLIT can do different source term geometry releases such as cuboid, ellipsiod, spherical or circle releases? Thanks

More than 12 input files for a concentration run

Hello, I currently have meteorological data files where each file corresponds to a single day. I need to run the model for a month with 30 files with a continuous release. As HYSPLIT limits the number of input meteorological files to 12 is there some way of circumventing this limit to run the model ...

Trajectory Advection Calculation

Hello, After reading about the trajectory calculations in Section 4.2 I have a few questions about the nature of these calculation. I am finding it difficult how one can intuitively justify the equation for the final position or come up with a derivation. 1. The final position is donated as P(t+dt) ...

Meteorological Data Text Profile

Hello, The HYSPLIT GUI allows us to get more detailed information from our meteorological data at particular times by using the Text Profile menu option. Is this feature available in Linux? The HYSPLIT tutorial page; (http://www.ready.noaa.gov/documents/Tutorial/html/meteo_data.html) does not provid...
