Plot Description:

This plot generates a comparison between two hourly ASOS observation values. The interactive chart version and raw data download also presents the most recent UTC timestamp for that given combination. Apps like these are very good at quickly seeing bad-data outliers :( Please review any results you find here to see if the values match what the reality may have been. Additionally, for the case of mean values, the presented timestamp is not of much use.
