| August 15, 2018: bullfrog(?) (Lithobates catesbeianus (?))|
This small frog is sunning itself on rocks beside a small artificial pond
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.
A Packet Radio Weather Station
|You can now use your
PayPal account to purchase instruments from IESRE.|
HERE is a link to a document describing how to build a simple
weather station that uses two Adafruit packet radio
boards with Arduino Pro Mini and UNO boards to send and receive temperature,
relative humidity, and barometric pressure data from DHT22 and BME280 sensors.
Build your own Stevenson screen
HERE is a link to a short document 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.
An Arduino-based Particulate Monitoring Station
HERE is a link to a document that details how
to construct an Arduino-based particulate sampling system using a laser-based Plantower
PMS5003 device that measures PM1, PM2.5, and PM10 concentrations. It includes
a DHT22 temperature/relative humidity sensor and an Adafruit data logging shield to
store data with a date/time stamp.
Air quality parameter monitoring for ozone and PM2.5 is back in Norristown, PA.
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
The Norristown site reports 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 documents relating to using Arduino microcontrollers have been moved to
their own web page.
Here is a link to some data resources from the Climate Literacy Network.
See our News link for information about a NASA Technical Memorandum which assesses 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 research projects.
Here is a link to a web 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 maps! The web page isn't a tutorial
on the KML "language," which is structured much like HTML, but there is a link to a nice online tutorial. There is also a template
for creating .kml files from Excel. There will be a permanent link to this page under the "How Do I...?" tab.
Find NOAA U.S. Historical Climatology and Climate Reference Network sites near you.
This online application lets you find USHCN and CRN sites within
a specified longitude/latitude box. You can display a list of the sites or generate a .kml file
for displaying the sites on a Google Earth global map.
Student Climate Science Inquiry and Research Projects
David Brooks' new document, Climate Science Inquiry and Research Projects for Students: Earth's Radiative Balance,
is a result of project development carried out during IESRE's
three-year, NASA-funded Climate Science Research for Educators and Students. This document
begins with an an introduction to Earth's radiative balance and using data loggers to collect data.
It then describes projects for measuring total solar radiation at Earth's surface, surface reflectance,
surface and sky thermal radiation, sky photography, and using existing data to examine climate
trends in the U.S. The PDF version of the document can be downloaded
This early version of the document represents a work in progress, but IESRE hopes that students
and teachers will find it helpful as they plan for science fair projects in 2014. Your comments and suggestions
are, as always, welcome.

2014 UPDATE ON CLIMATE DATA ACCESS APPLICATIONS
A SINGLE WEB PAGE is now available for accessing NOAA's Climate Reference Network data
through the end of 2013, including
additional insolation data and including a clear-sky model; the US Historical Climatology Network; 30-year climate normals (currently 1971-2000

to students, teachers, and my friends living in Thailand's tropical climate.
|This graph of barometric pressure recorded during Hurricane Irene in 2011
and "super storm" Sandy in 2012 dramatically illustrates the passage of
these storms through our area. Many sites, including a small airport site near IESRE were
not operational during the height of Sandy. Amazingly, we did not lose electrical
power during either of these storms even though both storms resulted in widespread
power losses – millions of people throughout the northeast lost power
