SEC/RPC HF Monitoring Yearly Summary Plots

The following summary plots have been generated from data collected for the NASA LWS HF Investigation of D-Region Ionospheric Variation Experiment (HIDIVE) project. The purpose of the project is to study the effects of D-region absorption on HF propagation. Currently, the standard time stations WWV (Colorado) and WWVH (Hawaii) are being monitored by the Space Environment Corporation in Providence, Utah, and at Bear Lake Observatory (BLO) near Garden City, Utah, and by RP Consultants in Klamath Falls, Oregon.
