Re: Error in vertical velocity and meteorological variables along the trajectory

In this case vertical levels are in normal order, so you don't need to reverse them. Revised script: #---- Set data folder datadir = 'E:/Temp' #---- Set output data file outfn = os.path.join(datadir, 'test_grib.arl') #if os.path.exists(outfn): # os.remove(outfn) #---- Read a GRIB data file infn = os...

Multi-color trajectory plot

Only one color can be assigned to a line in MeteoInfo, so we have to create multi-line pieces to fullfill multi-color trajectory plot function. Below is an example to plot a multi-color trajectory according to it’s height. Read the endpoints from the HYSPLIT output trajectory file, and create a laye...

Re: Validating rain along the trajectory.

MeteoInfo/MeteoInfoLab can read ARL data format and there is a sample script for getting meteorological data along trajectory (http://www.meteothinker.com/examples/meteoinfolab/trajectory/traj_meteo_data.html). Using MeteoInfoLab you can also do model verification by specific script. Also it's possi...

Re: Trajectory simulation

You need loading the meteorological data at end of Aug. for backtrajectory calculation starting from the first few days of Sep.

Re: cluster analysis for 5 year long data

TSV figure has been added in clustering function of TrajStat Java plugin from 1.4.3 version. So you can get a specified cluster number with the TSV figure using neweast MeteoInfo Java and TrajStat plugin version.

Re: Export RH2m from ARL GDAS data

The resolution of the data is 0.5 degree, so you got 3 data at 0, 0.5 and 1 degree east of longitude with [0, 1] longitude range.
