Use crosstrack data from whichever CERES instrument was operating in crosstrack
mode in the days or months of interest. This will maximize contiguous spatial
coverage in the field of view and gridded data. Rotating Azimuth Plane data has
large spatial sampling gaps caused by its optimization of angular sampling
coverage over spatial coverage. For 100km scale regions, spatial gridding
sampling noise is largest for SW fluxes. For daytime average 200 W m -2 SW reflected
flux, spatial gridding noise 10 W m -2 1 sigma for crosstrack data and
is 20 W m -2 for rotating azimuth plane data.
