Cosmic Pi North Pole Dataset 2024

Description

This raw dataset was gathered using a pair of Cosmic Pi detectors carried by the Transglobal Car Expedition across North America, to the North Pole and back to Greenland. To our knowledge this is the first ground level measurement of muons at the North Pole, beating the record previously set by the PolarquEEEst mission, which sailed up to a latitude of 82◦07′ (see https://cds.cern.ch/record/2743921/files/ncc11933(1).pdf for details).

The dataset comprises a portable Influxdb 1.8 export, with several sub datasets. 

We have the following data stored in the CosmicPiV1.8.1 measurement table:

  • measurement='CosmicPiV1.8.1',
  • DeviceID=cosmicdict['tags']['id'], Unit ID
  • latitude=cosmicdict['fields']['lat'], Latitude
  • longitude=cosmicdict['fields']['lon'], Longitude
  • Temp=cosmicdict['fields']['Temp'], Temperature in C
  • Hum=cosmicdict['fields']['Hum'], Relative Humidity in %
  • Accelx=cosmicdict['fields']['Accelx'], Acceleration, X axis in m/s/s
  • Accely=cosmicdict['fields']['Accely'], Acceleration, Y axis in m/s/s
  • Accelz=cosmicdict['fields']['Accelz'], Acceleration, Z axis in m/s/s
  • Magx=cosmicdict['fields']['Magx'], Magnetic field, X axis in Gauss
  • Magy=cosmicdict['fields']['Magy'], Magnetic field, Y axis in Gauss
  • Magz=cosmicdict['fields']['Magz'], Magnetic field, Z axis in Gauss
  • Pressx=cosmicdict['fields']['Press'], Atmospheric pressure in mbar
  • Altx=cosmicdict['fields']['Alt'], Altitude in meters
  • timestamp=cosmicdict['time'] Time

And we also have the frequency data (how many cosmic rays detected per second) here:

  • measurement='CosmicPiV1.8.1_freq',
  • DeviceID=cosmicdict['tags']['id'], Unit ID
  • geohash_pos="""+cosmicdict['fields']['geohash']+""", The geohash, a short code that represents lat & lon
  • event_count=cosmicdict['fields']['event_count'], The number of events in this second
  • timestamp=cosmicdict['time']) Time
