چکیده

As discussed in Sect. 3.2, it was difficult to compare GOSAT XCO2 with aircraft measurement data at some observation sites where there was a paucity of flight data on the day when GOSAT was scheduled to overpass. However, the temporal interpolation of aircraft-based XCO2 by a curve fitting method enables temporally matched cases to be obtained for all observation sites of CONTRAIL, NOAA, DOE, and NIES (41 sites). Based on Miyamoto et al. (2013), we attempted to fit aircraft-based XCO2 with the following equation (S.1) containing annual trend and annual / semiannual sinusoidal variations.

Comparison of Retrieved L2 Products from Four Successive Versions of L1B Spectra in the Thermal Infrared Band of TANSO-FTS over the Arctic Ocean

This paper concentrates on the calibration/validation of the Thermal and Near Infrared Sensor for Carbon Observation (TANSO)–Fourier Transform Spectrometer (FTS) spectra in the thermal infrared (TIR) spectral region (B4 band) over the Arctic Ocean. We have performed inter-comparisons of the retrieved L2 products from four successive versions of L1B products (V150, V160, V201, V203) to check the...
