Trajectory animation

The sample script for trajectory animation using MeteoInfoLab. import time fn = os.path.join(migl.get_sample_folder(), 'HYSPLIT', 'tdump') f = addfile_hytraj(fn) lon = f['lon'][:] lat = f['lat'][:] height = f['height'][:] #Plot ax = axesm() geoshow('country', edgecolor='gray', facecolor=(230,230,230...

Re: Average Meteorological data

you may try MeteoInfoLab to read and average ARL meteorological data. Following is an example script to read surface pressure data array (3 dimensions of time, latitude and longitude), and average along time dimesion (axis=0) to get the timely averaged pressure (2 dimesions of latitude and longtude)...

Plot trajectories on 3D earth

3D earth axes is supported from MeteoInfo 3.2.7. This is an example to plot trajectories on 3D earth surface. fn = os.path.join(migl.get_sample_folder(), 'HYSPLIT', 'tdump') f = addfile_hytraj(fn) lon = f['lon'][:] lat = f['lat'][:] alt = f['height'][:] * 1 #scale the height from earth surface pr = ...

Bugfixed for sub-hourly time resolution ARL data reading

In new released MeteoInfo 2.3.3, the bug for data extraction from sub-hourly ARL data (such as 10 minutes time resolution) was fixed. Also new version can read big ARL data structure much faster. In fact, ARL data label has no minute parameter to get right time stamp directly. For example, there are...

Re: Accommodation for no-leap calendars

I have no experience on no-leap canlendar, but I think hysplit need leap day as your testing result. So you need to convert no-leap canlendar to Gregorian calendar before writing the time in ARL data. In fact, MeteoInfo gets Gregorian time from data according starting time and hours (or other units)...
