Investigate ConMon plot issue with type uv235

[EdwardSafford-NOAA]

Time plots for data type uv235 reports a number of missing data warnings and only produces half of the expected plots (the lower 2) in each .png file. This is true for the plotstas_time_count.gs, plotstas_time_bias.gs, and plotstas_time_bias2.gs GrADS scripts.

Vertical plots for uv235 produce warnings in 2 of the 4 plots saying "Cannot plot data - all undefined values". This isn't fatal to the GrADS script but it is puzzling, since a no-data condition should be 0 value. Curiously the u235 and v235 plots run without producing any errors and do correctly produce 0 values. Probably related, the uvall plots produce errors from the vertical plots for the same regions as u235.

Type uv235 does not have many observations in a given cycle so it's possible this is related to a low-data condition.

Finally looking into this. The nobs_count files indicate occasional data for uv235. There is an explicit check in the plotstas_time_count.gs plot script to avoid plotting uv235. I've temporarily removed that because it looks like the data is valid, just very irregular. The entries in the base file (used for count validation) have been removed so no error messages should result. I'm going to run a few cycles like this and see what comes of it.

Note that the ConMon website menus are inconsistent with respect to uv235. Depending on what I find on the test runs, the website should be either corrected to include uv235 in all applicable menus or all references to uv235 should be removed.
