Another day, possibly the same hawk, for sure not the same gopher.

Coronavirus Hikes: July 2020

San Francisco PM2.5

Updated on Saturday, September 24, 2022

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.

Updated 2022-06-11 12:28:

The map is currently broken. The URL I use to download sensor data started returning a 500 error code at the end of may (Error: Server Error / The server encountered an error and could not complete your request. Please try again in 30 seconds.). This seemed like something Purple would need to fix. On closer inspection the error occurs after a redirect to https://purpleair-over-quota-2.appspot.com/ which sounds like too many requests (a 4xx error surely). With even more digging it turns out the download link is no longer supported (410 maybe then?) and so I'll need to migrate to the REST API to get this working again. I'm currently trying to get an API key and will get this fixed as soon as I can.

Updated 2022-06-13 17:28:

Purple Air were kind enough to issue me with an API key so the map is back to updating hourly.

West Portal Sunset

Updated on Saturday, February 19, 2022

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.
