Hi reddit! My main interests are doing science, writing books, and keeping a photographic record of the plants and animals on the land behind my office and residence. Since 1990, I’ve measured the ozone layer, the water vapor layer, solar UV-B, haze and various other atmospheric parameters. Many of my findings have been published in peer-reviewed scientific journals, and you can see a list of publications and some of the data at http://www.forrestmims.org. You can learn more about my research and interests in a Slashdot Q&A in 2014: https://features.slashdot.org/story/14/06/08/206220/interviews-forrest-mims-answers-your-questions Last year I talked to Slashdotters about airport security and electronics: https://hardware.slashdot.org/story/15/12/24/2147204/forrest-mimms-on-modern-air-travel-with-a-bag-full-of-electronics Recently I completed a nine-week assignment from NOAA to calibrate their world standard ozone instrument at Hawaii’s Mauna Loa Observatory (11,200 feet MSL). This was my 25th year to calibrate instruments at MLO. Let me know if you have any questions. I’ll be glad to respond for an hour or so and then must conduct the daily sun and sky observations. I’ll be back at 1 pm EST (10 am PST, 6 pm UTC) to answer your questions, ask me anything!
