Monitoring air pollution with Landsat satellite data

I'm trying to build an air pollution model. So far I have built one for point sources. Now I'm looking at monitoring air pollution with satellite images, based on the idea that every basic pollutant ...

Direct and Diffused component of shortwave radiation in ERA5 data

I am following the paper to calculate UTCI using ERA5 meteorological variables. https://link.springer.com/article/10.1007/s00484-020-01900-5?shared-article-renderer In the paper, the authors have ...

Can the absorbtion of infrared around the 650 wavenumber in water be a substantial cause of converting that spectrum range into other spectra?

CO2 absorbs around the 15 microns wavelenght or wavenumber 650, and radiates in the same but also a somewhat wider range. However, the top layer of the oceans seem to also convert that spectrum range. ...

Why is the Regener-Pfotzer maximum (radiation in upper atmosphere) above central California?

The site https://spaceweather.com/ has a section called Space Weather Balloon Data which shows the image below and says: The data points in the graph above correspond to the peak of the Regener-...

Amount of scattered vs. direct UV light from the Sun

I was wondering about the common saying that on a sunny, cloud-free day, depending on location, you can get a sunburn even when spending the whole day in the shadows. Already our blue sky provides ...

How does extra carbon dioxide in the atmosphere contribute to radiative forcing?

The CO2 absorption spectrum taken at 200 mmHg partial pressure, beam path length = 10 cm, resolution = 4 cm^-1 shows that light can only travel a couple hundred meters before being completely absorbed ...

How to convert solar radiation into equivalent evaporation

I have come across two (apparently) different equations for this purpose. One is mentioned in BASINS software code here $$Rad\_len [inday^{-1}] = \frac{SolRad[langleysday^{-1}]}{((597.3 - 0.57 * ...

Does depletion of Planck radiation intensity in the upper atmosphere mean that “CO2 has no impact on climate change”?

In his recent book, Rex J. Fleming asserts that "CO2 has no impact on climate change", or, as he summarizes on his website: There are now over a dozen books available on Amazon.com that point out ...

Looking at the brightest parts of the image how would one find the blackbody curve and wavelength maximum using a radiance calculator?

Look at the brightest parts of the photo and use a radiance calculator to find the blackbody radiation curve (show the plot of the curve) and the wavelength of maximum emission. How do ...
