you can get the real time data on Temp, Humidity, SOX, NOX from NASA portal. Just go the Giovanni satellite data bank and download the meteorological data of your interest
I believe that the HITRAN (high-resolution transmission molecular absorption database) might have what you are looking for. I have never used it though, but I know it is used to feed radiative transfer models for example. A quick Google search with terms HITRAN ozone temperature coefficient show some results.
Hi Siva actually its not about comparing gases with temp and humidity. I want to obtain temperature coefficients to nullify the impact of temperature change. Thanks
Could you be a little bit more specific in what you are asking for, please ?
Are you looking for cross sections, line intensities, concentrations. In case of spectral data, it would be helpful to know in what spectral region you are interested in. HITRAN would be a good resource as well as GEISA and the JPL compilation.
