    Considering the nature and structure of atmospheric weathering while the occurrence of daily dry periods in west and northwest of Iran by hossein Mir Mousavi, Masoud Jalali, enayet asadolahi

    Published 2021-12-01
    “…And the results gained of considering the atmospheric weathering, shows that the most clear rotational pattern in sea level is related to Siberia-Europe high-pressure panels and sometimes both of them that increase the rotation on the region and also, the local high-pressure reinforcement and there is a high altitude in atmospheric middle level which is derived from sample patterns and is placed on the studied region and these sample patterns are from omega, bi-polar and rex models that they are on Russia and Scandinavian countries with some changes. …”

    Calibration and Initial Results of Space Radiation Dosimetry Using the iMESA‐R by C. A. Maldonado, R. Cress, P. Gresham, J. L. Armstrong, G. Wilson, D. Reisenfeld, B. Larsen, R. L. Balthazor, J. Harley, M. G. McHarg

    Published 2020-08-01
    “…We present results of the calibration study along with initial on‐orbit data presented from the first operational iMESA‐R hosted on‐board Space Test Program Satellite 5 in a polar Earth orbit. The initial on‐orbit data demonstrate the ability to map the radiation environment, particularly the South Atlantic Anomaly and the auroral regions using total ionizing dose rate due to electrons of E > 1.5 MeV and protons of E > 25 MeV.…”

    AniMAIRE‐A New Openly Available Tool for Calculating Atmospheric Ionising Radiation Dose Rates and Single Event Effects During Anisotropic Conditions by C. S. W. Davis, F. Baird, F. Lei, K. Ryden, C. Dyer

    Published 2024-10-01
    “…Dose rate maps that evolve throughout the event are also shown, and it is found that each peak in the input pitch angle distribution generates a dose rate hotspot in each of the polar regions. AniMAIRE has been made available openly online so that it can be downloaded and run freely on local machines and so that the space weather community can easily contribute to it using Github forking.…”

    Can We Intercalibrate Satellite Measurements by Means of Data Assimilation? An Attempt on LEO Satellites by Angélica M. Castillo, Yuri Y. Shprits, Nikita A. Aseev, Artem Smirnov, Alexander Drozdov, Sebastian Cervantes, Ingo Michaelis, Marina García Peñaranda, Dedong Wang

    Published 2024-01-01
    “…Abstract Low Earth Orbit satellites offer extensive data of the radiation belt region, but utilizing these observations is challenging due to potential contamination and difficulty of intercalibration with spacecraft measurements at Highly Elliptic Orbit that can observe all equatorial pitch‐angles. …”
