The relevant housekeeping parameters for stability of the SWIR signal and thermal background are listed in the Table below. The reports on the SWIR housekeeping parameters are generated once per day from the TROPOMI L1B engineering products. All sensors are available at 1 Hz in the L1B engineering product, but averaged over 30 seconds for the zoom plots and averaged over a full orbit in the trend plots. The mean value is shown as a line and the range between the minimum and maximum value as a band.
