re #2, do you mean like from view, avt ext, re create?
As an example, please see http://tiggrweather.net/wxbarosummary.php
. I started in 4/2006, and the black holes between then and now used to have data. Don't know how it got lost. I got a lot filled in by downloading all WU data for a full month (day by day unfortunately), then putting that into a single file (something like 82010wu.csv), and then getting that to wind up in WD filling in a missing month of soup to nuts data. When my HD crashed so did my instructions and all the data I had previously loaded.
and re #1 do you mean to import into WD (instead of upload?)
The NOAA Report and Monthly Report normally created at 0000; e.g., dailynoaareport, etc. Yes, recreate and import.
