Why does WRF-Chem still produce various aerosol outputs even though I did not provide emission data?

Why does intensity drops as concentration increases?

Is there any reason for decrease in fluorescence emission intensity of HSA,BSA when increase the concentration ?

Receiving very less number of hits and events in acoustic emission tests?

I am doing a three point bend test with concrete specimen of dimension 280mm*90mm*90mm. I am putting 2 sensors near the notch with 3cms away from both the sides. the experiment ran for 20 mins but...

Why ICP-MS test for Teflon filters that collected PM2.5, show really high results in the millions of ug/g ?

I analyzed soil and ash samples using ICP-MS for 28 metals, then I resuspended those samples to collect PM2.5 particles in a filter using a selective inlet inlet. My only issue that Fe and Al...

How can I multiply values with standard distribution and with triangular distribution?

I am calculating emissions considering the uncertainty of the data to do Monte Carlo simulation. Some variables such as yields have normal, lognormal or even uniform distributions. These must be...

Can gas emissions (e.g. CO2) from industries turn into a resource/to reuse it?

As recent studies show, the high % global warming causes by gas emissions (CO2), mostly from industries. Can the CO2 turn into a valuable product/to reuse? How? for what can use? Any suggestion.
