Cosmic Pi North Pole Dataset 2024

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
