Below are some resources for researchers working on the radiative cooling field.
A Survey of Radiative Coolers
The following document contains a brief survey of radiative coolers. Please note that the information reflects the my knowledge of the field, and as such is not comprehensive or final.

Scotch Tape as a Radiative Cooling Standard
The following file contains near-normal reflectances (=1-emittance) of silvered and aluminized scotch tape for λ=0.3-30 μm, and angular and hemispherical reflectances of the metallized scotch tape for λ=1.2-30 μm.

Atmospheric Irradiance Calculator
This is a transmittance-based atmospheric irradiance model with a temperature correction applied to account for the total heat loss to the sky (space + the upper atmosphere). The correction accounts for the significant underestimation of the radiative cooling potential that results from typical use of the transmittance-based model in the literature. The full details can be found in the work, titled Accurately Quantifying Radiative Cooling Potentials: A Temperature Correction to the Transmittance-based Approximation posted here and on arXiv.
