View of Emigrant Pass Observatory (EPO) from the nearest road. Note the topography and scattered juniper forest.
EPO is a weather station on top of a 150m borehole, which can be used for investigating the energy balance of the Earth's surface, reconstruction of paleoclimate from borehole temperatures, and other geothermal investigations.
EPO is maintained by the Thermal Geophysics Group at the University of Utah.
More information, description, etc. is coming "soon".
The most recent data retrieved by telemetry is available here.
A single file of all data from EPO since November 2004 is available here. This file is appended to each day after a download. Data format is fixed-width, blank-delimited fields. The order of fields, with units, is:
