Weather charts for September 2006
One thing that had long bugged me about my weatherstation set-up was the position of the thermo-hygro sensor unit. Most of the time it worked fine but on a sunny summer evening, albeit a rare event, the sun would shine directly onto the unit and give grossly exaggerated temperatures. Also, in March I had rerouted the cabling which left it trailing across the wall for about five or six feet. At last, on the 3rd of this month, I finally got around to moving it and it is now closer to the eaves and next to the cable exit from inside the house. I may still have to fit some sort of shielding to fully protect it from direct sunlight but that will be a job for next summer when I will be able to see exactly how things look in the new position. A problem also occurred this month with my data file. For several days I couldn't view the data as normal in the Heavy Weather program. The pretty display showing the current data was fine, but whenever I tried to view the raw numbers I got messages about invalid dates. At first I blamed Windows then Heavy Weather before finally figuring out that my data file had become corrupt. I would have thought that Heavy Weather would have been able to recognise this and tell me, after all, it was the program creating the file in the first place. The only solution was to scrap the exisiting file and start again as even using a backup it just skipped the missing data and carried on from the present. The data shown here is, therefore, reconstructed from several files with only a few samples missed between 12:30 and 13:30 on the 17th.
