QA Request - Infomation about the Dropped Circles

[rectheworld]

In the notebook 1.1-circles-to-many-noaa-stations-usa-weather-data, circles are dropped that do not have weather data.
Effectively, we go from 4585 unique lat long combinations in the input file to 3500 unique lat lon combinations in the output file.

note: unique lat lons calculated by:

df['lat'].astype(str) + df['lon'].astype(str)

That is a big drop in unique lat lons so i would like to know.

• How many circles were dropped?
• Can we create a map of their location? Are the concetrated in an area?
• What years are they from?
• How far away was their closest station?
• How populated was their rain data?
• How populated was their temp data?
• How populated was their snow data?

This data can be presented in a notebook or in the comments on this issue.
