Ongoing Projects
| Project | Road Vehicle Emission Factor |
|---|
| Category | Traffic Emission |
|---|
| Status | Online - Beta |
|---|
| This application is based on the draft report prepared by the Automotive Research Association of India on "emission factor development for indian vehicles" revision 4, dated august 8, 2007. |
|
| Project | Solar Insolation Calculator |
|---|
| Category | Atmospheric Dispersion Modeling, Renewable Energy |
|---|
| Status | Online - under development |
|---|
This application is based on the standards equations for the Sun Declination with respect to latitude and longitude data. The other parameters considered are refraction correction and cloud cover. The calculator is now being calibrated.
This application is provided with Google Map – zoom and click at your station and application will plot the annual insolation graph. |
