I am looking for TEC measurements from satellites for the F-layer Ionosphere. The Global Ionosphere maps are available for real time. But, the TEC map of a past date is hard to find. These are the global maps of 3 hourly durations in a day.
Hi Adarsh,
You can find GIM-TEC 2 hour resolution TEC data via this ftp links in IONEX file format.
ftp://cddis.gsfc.nasa.gov/gps/products/ionex/
year between 1998-2016
The availability of GPS data as well as other satellite data allows many organizations to be able to compute, or better to model, global maps of TEC and VTEC. So you may find many web sites from where to download these maps: here it is one example:

Hi Adarsh Dube
I suggest to try the GIM data from the following link :
ftp://ftp.unibe.ch/aiub/CODE/

I meet the same problem as you now. Where did you find global Ionospheric maps ?
I did not use any map. I followed observations with ground receiver's data of IGS network.
