San Francisco PM2.5

Updated on Tuesday, September 22, 2020

San Francisco PM2.5

This post is updated hourly with a PM2.5 (2.5 micrometer or smaller particulate matter) map of San Francisco.

The PM2.5 data comes from the Purple Air API. The map uses one hour average readings from outdoor sensors and interpolates each point in San Francisco based on the inverse of the distance to the four closest sensors. The color scale is green to yellow (0-50), yellow to orange (50-100), orange to red (100-150) and red to purple (150-200+). San Francisco is plotted using elevation contours from DataSF.

West Portal Sunset

West Portal Sunset

Spectacular sunset the other night, the kind where I really wish I'd left a timelapse running an hour earlier. This time I did! It was just a test run of a new GoPro Hero 8 Black to see what the nightlapse mode is capable of. I left everything on auto, including the interval, which I thought was an odd thing to have an auto mode for but that it might produce some interesting effects. Nope. The GoPro does a nice job of ramping down the shutter speed and ramping up the ISO, but it just randomly toggles the interval between one and two seconds occasionally which just glitches the video. So won't be using that mode again.
