I would really appreciate some pollen & other allergen info as well.
pollen info shot to the top of my concerns end of June in Portland. I haven't been hit like that for years and I couldn't find any reliable info (reports were often conflicting) on the net. I really like the weatherspark interface and would love a pollen map feature. Considering getting a 2nd hand microscope and wiping window sills but wouldn't know how to upload that data in a useful way.
Would prefer a pollen map myself. Either way, they should really reference/describe the scale and be very specific in the graphing, especially over time. The pollen graphs that @Anonymous provided a link to bellow are an example of horrible horrible graphs that should not even be considered an example, lest they taint your mind.
As a hayfever sufferer, pollen charts would be fantastic. Ideally today's pollen count so I can explain why I'm sneezing my face off, and a forecast so I can up my antihistamine dosage.
A starting point: https://pollen.aaaai.org/nab/index.cfm?p=allergengraph&stationid=2&startdatevalue=3650
Add drilldown, year-by-year overlay for comparison, etc.

Pollen charts would be great to add, will look into that.
