Book Description
In this report, an atmospheric model for the calculation of riometer absorption during Polar cap absorption events is given; specifically, an atmospheric response function is calculated and tabulated at necessary altitudes for (1) each month of the year, (2) day and night, and (3) 60 degrees N and 90 degrees N latitude. In addition, a polynomial fit to the atmospheric response function is given in terms of polynomial coefficients. Also tabulated for the conditions above are the collision frequency, atmospheric depth, and scale height.

The Calculation of Riometer Absorption and an Approximate Connection Between Riometer Absorption and Solar Proton Fluxes During Nighttime PCA Events

Category : Atmospheric models

Pages : 44
Book Description
In this report, the calculation of riometer absorption during several PCA events of particular interest is presented. These calculations are based on earlier work in which an improved effective recombination coefficient was derived and an atmospheric model for (1) each month of the year, (2) day and night, and (3) 60 deg N and 90 deg N latitude was presented. In this report, the calculated values of riometer absorption are presented for 5 PCA events: 2 Nov. 69, 7 Mar. 70, 25 Jan. 71, 2 Sep. 71, and 3 Aug. 72. The calculated values of riometer absorption are compared with experimental values measured for both day and night conditions at Thule, Greenland. An approximate connection between riometer absorption and the square-root of the proton flux for nighttime conditions is presented. This relationship, which has previously been applied only for daytime conditions, is discussed both on a fundamental level and on the level of verification by comparison with experiment. In addition, the basic equation widely used to calculate riometer absorption is compared with the original Sen-Wyller result.
