Thule Neutron Monitor (THUL)

The detector is located at Thule Air Force Base, Greenland

Standard 18-NM64 neutron monitor in 3 6-tube sections. Current configuration is 9 BF3 and 9 3-He counters. Prior to June 2001, Thule was a Standard 9-NM64 neutron monitor in three three-tube sections with all BF3 counters. All 18-tube data has been normalized to the older 9-tube count rate.

Conditions for Use of Data

    You are welcome to use University of Delaware neutron monitor data under the following conditions:

    1- You agree to acknowledge the source of data in any publication; for example:

    The neutron monitor data from Thule are provided by the University of Delaware Department of Physics and Astronomy and the Bartol Research Institute.

    2- You agree to send a copy of any paper using these data to:

    Prof. Paul Evenson,
    Department of Physics and Astronomy
    204 Sharp Lab, University of Delaware
    Newark, DE 19716, U.S.A.

    3- Commercial or industrial use of the data is prohibited without previous agreement with the PI of the station (see name and address above)

    4- You may share these data with colleagues, provided you inform them of these conditions.

    In the event there are future modifications to the data, NMDB will always return the most recent version. We will document any significant changes in the station notes.
