Ionospheric Correlation Time

Correlation time (or relaxation parameter) for the ionospheric data assimilation.

each .nc file in this folder corresponds to a particular bin. 

Binning in season:          

0=month 1,2,11,12
1=month 5,6,7,8
2=month 3,4,9,10

Binning in F10.7 solar flux:

0=0-100 s.f.u
1=100-200 s.f.u.
2=200-350 s.f.u.                   

Example: 
The name of the .nc file:       
Corr_Time_season_02_sf_01.nc  
would correspond to season with bin 2, solar flux with bin 1.

Inside of the .nc files:

Mlons=array of geomagnetic longitudes (degrees)
Mlats=array of geomagnetic latitudes (degrees)
corr_time=array of size (nlon, nlat), is a map of correlation times (hours)
