|Ruby-throated hummingbird (female), (Archilochus colubriso)|
August 7, 2014. The female lacks the red throat of the male. We often see these
tiny birds flying around our property and feeding at flowers. But, it is unusual
to catch one perching and preening. Their normal flight speed is about 50 kph
and faster when they are diving. Their average length is about 9 cm and they
weigh only about 3 g. The female is slightly larger than the male.

Here is a link to David Brooks' new document, Arduino-Based Dataloggers: Hardware and Software.
This document shows how to build and program a four-channel 16-bit datalogger based on an Arduino microcontroller.
This datalogger is suitable for use with IESRE and other sensors, including some commercial pyranometers which
have a smaller voltage output than IESRE pyranometers. This logger also makes it possible to do a better job of monitoring
surface reflectance from dark surfaces with IESRE pyranometers used in pairs as upward- and downward-facing radiometers.
Data files are stored on an SD card. The cost of this project is roughly $75, which is much less than the cost of
commercial loggers with comparable resolution. This is Version 1.0 of this document, which undoubtedly
will be revised, corrected, and updated. However, this version
has been put online in response to a lot of recent interest in such a project. As always,
your comments, suggestions, and questions are welcome!

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
