[ncl-talk] Regridding OMI NO2 to WRF domain

[Rick Brownrigg]

Did you get the proper/expected lat/lon grid otherwise, despite the result
being 3D. What is that 3ed dimension? From the long_name, it sounds like
elevation/altitude/level, Do you need to sum, or average, or slice that
dimension to reduce to a 2D grid?
