This lesson reinforced some good concepts about model initialization, and I found it particularly interesting learning how water vapor imagery specifically can be so instrumental in seeing how well a model initialized; however, the examples used in the lesson, in my opinion, were not as concrete and black and white as the presenter claimed, making it difficult to arrive at the same conclusion about whether to modify data or not, and if so, how. Good lesson in concept - not as great in practical application.

Interesting module. Quite an advanced course which is best tailored to meteorology personnel that have the opportunity to directly modify NWP initial condition data in the model's assimilation chain or/and have access to synthetic WV imagery in their forecasting office. Some of the differences between WV, PV and SWV was not always that clear to pick out since some of the PV isolines sometimes obscured the WV imagery underneath and subjective interpretations sometimes differ. Forecast challenge 2, question 13 had no satellite imagery. I therefore used satellite imagery from question 12 but analysis locations b and c were not highlighted on this imagery. That being said, quite instructive module which introduces one to synthetic WV imagery (analogous to model simulated radar reflectivity as a proxy to radar) and when or when not to trust model PV/SWV fields when compared to WV imagery.
