The tropomi smoothed boundary conditions use a -15 day temporal smoothing to generate the bias correction. There are two periods in the tropomi record with greater than 15 day gaps in observations (21 and 29 day gaps). This causes anomalously low boundary conditions for these periods with corrections that can reach >100ppb corrections. In this PR, I update the temporal smoothing to default to -15 day smoothing, but in the case of data gaps, we fill in grid cells with the -30 day smoothing.
