Instesre.org Website Review

e-mail: [email protected] some of the work described on this site has been made possible by support from the national science foundation, the national aeronautics and space administration, the national oceanic & atmospheric in our yard. i think it is a bullfrog, but i'm not sure. this frog is about 3-4 long. bullfrogs can grow to more than 8 long. it yipped at me and dove back into the water when i got too close. and uno boards to send and receive temperature, relative humidity, and barometric pressure data from dht22 and bme280 sensors. showing a stevenson screen i built using vinyl shutters (from home depot) and some 1 x 12 pine boards. commercial stevenson screens are very expensive, so it is worth looking into making your own. you will need some basic woodshop equipment. details how to construct an arduino-based particulate sampling system using a laser-based plantower pms5003 device that measures pm1, pm2.5,. ------------------------- air quality parameter monitoring for ozone and pm2.5 is back in.       the dep monitoring site in norristown is only a few miles from my home. in 2015, pm2.5 monitoring was discontinued at this site, but it has now restarted. real-time aqi values from monitoring sites in pennsylvania can be found here only 1-hr ozone and pm2.5 values. these values have been used in recent studies of the relationship between air quality and sky color. ------------------------- links to several docu*ents relating to using arduino microcontrollers memorandum which as*esses an inexpensive method for measuring total column water vapor based on a 2011 paper by mims, chambers, and brooks. links to the original bams paper and the nasa technical memorandum are provided. these measurements are ideal for student page that shows how to create a .kml file that will display the location of all of noaa's climate reference network sites on google earth's global map. you can tag each site with additional information. this kind of display is a big improvement over using 2-d
