Sentinel-5P provides atmospheric measurements, relating to air quality, climate forcing, ozone and UV radiation with high spatio-temporal resolution. Its data is used for monitoring of concentrations of carbon monoxide (CO), nitrogen dioxide (NO2) and ozone (O3) in air as well as for monitoring of UV aerosol index (AER_AI) and different geophysical parameters of clouds (CLOUD). EO Browser serves level 2 geophysical products. The TROPOspheric Monitoring Instrument (TROPOMI) on board of the satellite operates in the ultraviolet to shortwave infrared range with 7 different spectral bands: UV-1 (270-300nm), UV-2 (300-370nm), VIS (370-500nm), NIR-1 (685-710nm), NIR-2 (755-773nm), SWIR-1 (1590-1675nm) and SWIR-3 (2305-2385nm). Its spatial resolution is below 8km for wavelengths above 300nm and below 50km for wavelength below 300nm. It covers almost the whole globe (95 % coverage for latitudes in the interval [-7°, 7°]).
The Landsat program is the longest running enterprise for acquisition of satellite imagery of Earth, running from 1972. The most recent, [Landsat 8](http://landsat.usgs.gov/landsat8.php){:target="_blank"}, was launched on February 11, 2013. Landsat-8 data has 11 spectral bands with spatial resolutions ranging from 15 to 60 meters. The names of the Landsat-8 bands at your disposal are *B01*, *B02*, *B03*, *B04*, *B05*, *B06*, *B07*, *B08*, *B09*, *B10* and *B11*.
The Aerosol Index (AI) is a qualitative index indicating the presence of elevated layers of aerosols in the atmosphere. It can be used to detect the presence of UV absorbing aerosols such as desert dust and volcanic ash plumes. Positive values (from light blue to red) indicate the presence of UV-absorbing aerosol. This script visualizes AER wavelength pair 340/380 nm.
