Title: Seasonal maps of the TanSat v2 dataset using the IAPCAS retrieval algorithm

Description: These images show the expected seasonal plot of the v2 TanSat data covering the time period March 2017 to February 2018. The expected seasonal variation of CO2 with a strong summer uptake by northern hemispheric forests and a peak-to-peak seasonal amplitude of +/- 3–4 ppm, is noted. The observed seasonal signal in the southern hemisphere is muted due to the much smaller amount of land masses. Gaps in coverage are the result of the quality filter applied. Enhancements in CO2 over emission regions, such as Eastern China, are less obvious in these seasonal maps.
