The Blanket Effect is intended for others to learn about weather modification and its related subjects in an easy to understand way. Started in 2005, this blog is a work in progress as the technology advances

Multiple Instrument Studies of Chemical Releases and Heating at Arecibo

PDF document)


MAR 1994


The Combined Releases and Radiation Effects Satellite (CRRES) Puerto Rico experiments carried out during June and July 1992, provided an opportunity to observe the dynamics and evolution of high-altitude chemical releases at middle latitudes.

Among the experiments that were conducted for the program, three large barium payloads were released into the dawn F region -- two into the natural ionosphere and one into an ionosphere modified by HF heating.

Extended periods of HF modification prior to the rocket launches also provided an opportunity to study heating effects, per se.

This report reviews some preliminary results from three participating instruments:
(1) ion-line mapping made by the Arecibo incoherent scatter radar,
(2) HF backscatter characterization and tracking of the barium cloud, and
(3) transionospheric propagation diagnosis of large and medium scale structure produced by heating and the barium releases.

The data that are reviewed are primarily observational and are presented with a minimum of physical interpretation. Recommendations are made for further analysis of much of the data.
