| 2017 partial solar eclipse in Pennsylvania|
The August 21 partial eclipse (about 75% coverage) was somewhat
of a bust where I live, but the sun was occasionally visible through
breaks in the mostly overcast conditions. This image was taken with a
Canon PowerShot SX120IS, using manual settings of ISO100, f5.6,
1/2500 s, full 10x zoom, at 13:47 EST, within a
couple minutes of
The graph shows that even though there was no readily apparent
darkening under an overcast sky, the total insolation (solar radiation
reaching the surface) was significantly reduced during the eclipse. The
insolation data were collected with a Kipp & Zonen SP-Lite (the red line)
and one of IESRE's pyranometers.

This document shows how to use a small TFT display (ID 2088 from www.adafruit.com) to generate simple
bar graphs. A code example shows how to update and graph eight pairs of temperature and relative humidity values
from a DHT22 sensor. Code is also given that shows how to
include storing the temperature and relative humidity data to an SD card with a date/time stamp, using the ID 1141
data logging shield from www.adafruit.com. Code is given for displaying small
.bmp images on the display.
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

|This graph of barometric pressure recorded during Hurricane Irene in 2011
and "super storm" Sandy in 2013 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
