Earth Surface and Atmospheric Reflectivity Since 1979 …
WebThis proposal concerns the production of a continuous ultraviolet reflectivity data record for Earth's surface and atmosphere using multiple satellite data records dating back to 1979. The scene reflectivities of Earth at blue and ultraviolet (UV) wavelengths (320 nm to 415 nm) are low over most surfaces (except ice and snow), and are almost ... WebThe solar radiation that passes through Earth's atmosphere is either reflected off snow, ice, or other surfaces or is absorbed by the Earth's surface. Emitted LONGWAVE Radiation … how to install addons for gmod
Spectra of Earth, Venus and Mars. The left figure shows the reflection …
WebDue to reflection by the atmosphere, clouds, and Earth's surface we can approximate that 70% of solar energy incident on the edge of the Earth's atmosphere is actually absorbed by the Earth. Taking this into account, the actual average amount of solar energy absorbed by the Earth amounts to: H = 0.7 × 340 W m 2 = 238 W m 2 Energy to the Surface WebApr 11, 2024 · The standard deviation of the reflection ratio is less than 3%. For 328 nm, 335 nm, 340 nm, 460 nm, and 490 nm, the mean values are close to one, and the relative radiometric bias estimated through EMI-2 and TROPOMI intercalibration is less than 3%, and for other wavelengths, the biases are less than 6%, except for 416 nm, which behaves … WebAug 1, 2024 · Radiative forcing is calculated in watts per square meter, which represents the size of the energy imbalance in the atmosphere. On the right side of the graph, radiative forcing has been converted to the Annual Greenhouse Gas Index, which is set to a value of 1.0 for 1990.
