Meteor Radar Observations

The Canadian Meteor Orbit Radar (CMOR)

Daily Operations

 

CMOR is a highly automated radar. Each day, automatically generated state of health data, plots and initial data summaries are produced and emailed to users. This high fidelity reporting capability allows CMOR to stay on the air with a duty cycle in excess of 95%. An example of the daily output summaries from CMOR is shown below for the 2009 Geminid shower peak:

Daily sporadic and shower fluxes and equivalent daily averaged ZHRs are computed

flux          20091212
freq          29.850 MHz
solarlon      260.46 deg
sporadic      1.35e+00 1/km^2/hr (meteoroid mass > 1.1e-07 kg)
shower GEM    5.52e-02 1/km^2/hr (meteoroid mass > 1.8e-07 kg)
              8.57e-02 1/km^2/hr (meteoroid mass > 1.1e-07 kg, using s = 2.0)
ZHR GEM       95.0

 

Additionally, the numbers of measured orbits per hour and the strength of the remote station UHF links are computed and link strength is displayed graphically:
