Temperature scale update on maps

When I added Canada and Australia, I dropped the local Contiguous USA local maps that were searchable by zip code, because the Canadian and Australian zip code differences would not let the program run for the whole package. I have now returned the local zip code searchable forecasts for just the contiguous US and will not be having the searchable local maps feature for the Canadian and Australian coverage areas.

I have added more delineations to the temp color scale, and moved it to the left side as requested by some users of my maps, compressed the top to allow the whole map to be viewed on smaller screens and/or with out so much scrolling when changing dates, countries, or parameters. The input data remains unchanged, as do the csv files drawn from the raw data to create these maps. Only the color scaling was changed, from the standard that the NWS was using, to a more natural color scheme based on vegetation reactions to temperatures, for the easier use by farmers. Clip of the new scale below.

New

From 0C to 5C when roots grow, but no grass top growth occurs the white (probable frost band) to yellow bands, from grass emergence to cooler season pea and legume sprouting the further blending from light blue to light green, and soil planting temps for most agricultural field crops in the light green to darker shades around 20C, then the optimal temps for photosynthesis for mature plants and most field crops is centered on a forest green at ~72 degrees F.

From about 78 degrees F to 82 degrees F a yellow band to show slight stress might be present in low humidity conditions, fading to browns from 83 to 92 degrees F reflecting probable stress in more humid conditions, and definite slowed growth in dry conditions, then from human body temperature and up, in the red shades that the NWS used for every thing above a comfortable 75-80 degrees F to be really scarey for the AGW meme.

I am hoping that this finer graduation of temp color scales will end most of the confusion that resulted in trying to  read the massive range of the original yellow through orange, red to pink that covered an 80 degree F range or a 40 degree C range that tricked the eye into seeing it as almost all the same.

At 9:00 pm Phoenix time yesterday (2-17-2013) we started the re-upload of the  maps with the new temperature color scale and the local area maps will be once again available, in 24 hours the server has regenerated 4 months of the maps from June 1,2012 through end of September 2012. We originally re-did the month of May 2012 with out converting the North American maps so we could see the difference, I chose to leave them that way so you could see the difference for your self. If you open one of the maps say May 15th http://www.aerology.com/?location=Usa&mapType=Tmax&date=5%2F15%2F2012 and flick between the North American and either the Canadian or USA maps you can easily see the difference.

It should take another ~10 days for the server to create all of the needed maps to cover all of 2013, 2014, and 2015, if all goes well and there are no unexpected interruptions, (took a 36 hour hiatus to make the remaining csv files that will allow  us to continue to load maps until the 19 year limit of the process from the most recent data we have is reached, 2001 +19 = late December of 2020).  We will be updating (the on site) color scale presentation as soon as the map re-production is up to ~ the current date, along with the additional graphic additions and changes to compress the top, put the temp scale on the left and make it work better for you as requested.

For farmers and the associated markets that depend on their production to survive, shifting from the High temps and the Precipitation patterns for each day as you go through the growing seasons of your choice should alert you to times when the heat and dryness combine to create crop yield decreases, like we had last year. If you review the July and August temps and precipitation forecasts on my pages it will school you on what to look for.
