The TROPOMI surface DLER V2.2 product provides the directionally dependent Lambertian-equivalent reflectivity (LER) of the Earth's surface as observed by TROPOMI. This database contains data for 21 one-nm wide wavelength bins ranging from 328 to 2314 nm. Alongside the traditional non-directional LER field, the product includes the directionally dependent Lambertian-equivalent reflectivity (DLER), which accounts for the viewing-angle dependence of surface reflectance due to the BRDF of the surface. This approach improves surface reflectance accuracy, particularly at longer wavelengths.
Dataset Specifications
The surface DLER is available for each month of the year and for the following wavelengths: 328, 335, 340, 354, 367, 380, 388, 402, 416, 425, 440, 463, 494, 670, 685, 697, 712, 747, 758, 772, and 2314 nm. These wavelength bands are more or less monochromatic (one nm wide in most cases) and suitable as input for the retrieval of most atmospheric species. The resolution of the database grid is 0.125°×0.125°.
