Examples of the data are as follows:

EPOCH:

data.epoch.data[0] =   1363496400

 

This data is presented as number of seconds since January 1, 1970 in UT. The example above converts to 2013-03-17/05:00 UT. There are 1200 time values stored in each file.

 

LATITUDE:

data.latitude.data[0] = 45.0000

 

This data is the geographic latitude in degrees of the 400x400 grid of data points. There are 400 latitude values stored in each file.

 

LONGITUDE:

data.LONGITUDE.data[0] =  180.000

 

This data is the geographic longitude in degrees of the 400x400 grid of data points. There are 400 longitude values stored in each file.

 

CONDUCTANCE:

data.conductance.data[0] = -1.0000000e+31

 

This data is the Hall conductance in mho measured at 45 deg latitude, 180 deg longitude. The value in this example indicates that no conductance was measured here. A valid value would be something in the range of 0.00043800000 to 88 mho. There are 1200x400x400 conductance values stored in each file.

 

ENERGY FLUX:

data.eflux.data[0] = -1.00000e+31

 

This data is the energy flux in ergs/cm^2/s measured at 45 deg latitude, 180 deg longitude. The value in this example indicates that no energy flux was measured here. A valid value would be something in the range of 0.01 to 1100.0000 ergs/cm^2/s. There are 1200x400x400 energy flux values stored in each file.

 

ENERGY:

data.energy.data[0] = -1.00000e+31

 

This data is the energy in keV measured at 45 deg latitude, 180 deg longitude. The value in this example indicates that no energy was measured here. A valid value would be something in the range of 0.01 to 22 keV. There are 1200x400x400 energy values stored in each file.

 

2. README for text file Data to be published alongside “Mesoscale Contributions to Auroral Energy Deposition and Conductance During the 2013 St. Patrick’s Day Storm” by Christine Gabrielse et al. in the Journal of Geophysical Research.

This README applies to the following files:

   march172013_fortyukon_photometer_products.dat

   march172013_pokerflat_photometer_products.dat

Header information in the files describe the contents. 

These are the photometer derived data taken on March 17, 2023. They include the time [UT], energy flux (Q) [ergs/cm^2/s], average energy (Eavg) [keV], and oxygen scale factor (fo).
