Systematic Correlation of Local Diurnal Daylight Variations with Local MUF

It is well understood that MUF follows the degree of daylight in a general sense, but there has been little study on the correlation between local diurnal daylight conditions and local MUF.  It is believed that encouraging this sort of study in a large number of locations will aid in the predictability of HF radio propagation.  Interior Alaska, because of its high latitude, has a large variation in diurnal light between summer and winter, and is an ideal location for doing this study.  For many months, we have been collecting diurnal light intensity from a northern facing photoresistor, giving us many data points that we can correlate with local ionosonde MUF data.
