These pictures show the SCIAMACHY nadir (green) and limb (blue) measurements of today and tomorrow near Cabauw (NL), where a validation campaign will be performed for NO2 and aerosol. The observation times (UT) are indicated in the limb measurements, the (closest) nadir measurements are performed typically 7 minutes later. Note that the geolocation of the limb measurements is based on the projection of the tangent heights. The actual observed air mass is larger.
Each block in the picture contains a series of nadir or limb measurements. The ground pixel sizes for individual measurements depend on the orbital position and the retrieved trace gas.
The nadir measurements are used to derive trace gas columns of O3, NO2, SO2, BrO, OClO, H2CO, N2O, CO, CO2, CH4, H2O, aerosols, UV index and clouds, the limb measurements are used to derive trace gas profiles of O3, NO2, BrO, H2O, N2O, CO, CH4, CO2, p/T profiles and aerosols.
The geolocation information is obtained from the SCIAMACHY operations web site.
