Title: 4D Ionosphere Post by: Sam KS2AM on May 02, 2008, 02:02:48 PM Google Earth + CAPS data = Great presentation of ionospheric TEC, MUF. etc. AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
"In addition to total electron content, the 4D model also can be configured to display available radio frequencies, maximum usable frequencies, and the critical "bounce frequency" of the ionosphere's f2-layer—terms well known to hams and other experts."" http://science.nasa.gov/headlines/y2008/30apr_4dionosphere_launch.htm (http://science.nasa.gov/headlines/y2008/30apr_4dionosphere_launch.htm) Sam / KS2AM |
