Parameter #2

Name

Huancayo Hourly Average

ParameterKey

Column 4

Description

Huancayo pressure corrected counts per hour, prescaled by 100
Periods with no data are indicated by -1.0

Caveats

For true counts per hour, the value given must be multiplied by 100. Corrections for geomagnetic drift affecting the cutoff have not been applied

Huancayo Cutoff Drift Corrected Hourly Average

ParameterKey

Column 5

Description

Huancayo counts per hour, prescaled by 100 and corrected for
pressure and geomagnetic cutoff drift due to secular changes
in the geomagnetic field.
Periods with no data are indicated by -1.00

Caveats

For true counts per hour, the value given must be multiplied by 100.
