“…It allows the estimation of low (electrons, highenergy protons, mesons etc) and high (neutrons mostly) LET components of onboard aircraft radiation fields and the total exposure level. Recently, in [5] reported that in a series of long term measurements performed with this equipment LN10-1 onboard of Chech Airlines aircraft during the year 2001, they were able to register the solar cosmic ray event GLE60 on April 15, as well as the Forbush Decreases (FD) on April 12 and November 06, 2001. Based on the above, the use of a small and light UAV, flying at high altitudes and carrying on board a detector for monitoring radiation levels and additionally telecommunication transceivers, can open new measurement structures at some important altitude levels, over an extensive geographical area, offering complimentary services to the appropriate terrestrial, aircraft, and satellite probes [2]. The main advantages of having the LET spectrometers on the UAV are their favorable physical attributes (very small dimensions, light weight, very low power consumption), the opportunity their measurements will provide to determine the impact of GLEs on the atmospheric radiation environment, and the possibility to obtain a quantitative assessment of the induced changes.…”

“…For this purpose a comprehensive database is being generated, using aircraft measurements made by a Low-Let Radiation Spectrometer (LoLRS), to enable a multivariable global mapping of doses and Linear-Energy Transfer spectra at aviation altitudes. As described by [2], this data base will be used to generate a detailed description of the cosmic ray induced particle environment and determine the effects from long-and short-term variations.…”

A proposal is presented for flying a light Unmanned Aerial Vehicle (UAV) carrying a Linear-EnergyTransfer (LET) radiation spectrometer and networked to the Athens Neutron Monitor Data Processing Center (ANMODAP), active in Space Weather Events (SWE) forecasting. The ANMODAP receives data from a large number of remote neutron monitor (NM) stations, provided in real time over the Internet, together with satellite data. Through this project, the ANMODAP forecasting capability will be increased with the collection of data at high atmospheric altitudes over Greece by the LET radiation spectrometer, carried on the specially designed UAV. The advantages of this spectrometer are its very small dimensions, light weight, and low power consumption. The UAV, powered from photovoltaic generators, flying at high altitudes with propellers on small electrical motors, and carrying simple networking equipment, will achieve long range telecommunication links with a terrestrial footprint larger than the area of Greece.

“…(134)(135)(136)(137) A perhaps counterintuitive effect is that energetic particle radiation can diminish during/after a geomagnetic storm (a Forbush decrease) because the CME can block Galactic Cosmic Rays, which leads to a complex balance of effects. (138) Radiation storms have a technological (134,(139)(140)(141) and biological impact (due to the fact that the radiation is ionizing). (142,143) While unlikely, mandated crew dose limits could be reached in part due to severe space weather; (141) the wider impact has also been examined.…”

The Economic Impact of Space Weather: Where Do We Stand?

et al. 2017

Space weather describes the way in which the Sun, and conditions in space more generally, impact human activity and technology both in space and on the ground. It is now well understood that space weather represents a significant threat to infrastructure resilience, and is a source of risk that is wide-ranging in its impact and the pathways by which this impact may occur. Although space weather is growing rapidly as a field, work rigorously assessing the overall economic cost of space weather appears to be in its infancy. Here, we provide an initial literature review to gather and assess the quality of any published assessments of space weather impacts and socioeconomic studies. Generally speaking, there is a good volume of scientific peer-reviewed literature detailing the likelihood and statistics of different types of space weather phenomena. These phenomena all typically exhibit "power-law" behavior in their severity. The literature on documented impacts is not as extensive, with many case studies, but few statistical studies. The literature on the economic impacts of space weather is rather sparse and not as well developed when compared to the other sections, most probably due to the somewhat limited data that are available from end-users. The major risk is attached to power distribution systems and there is disagreement as to the severity of the technological footprint. This strongly controls the economic impact. Consequently, urgent work is required to better quantify the risk of future space weather events.

U.S. Government shutdown degrades aviation radiation monitoring during solar radiation storm

et al. 2014

The U.S. Government shutdown from 1 to 17 October 2013 significantly affected U.S. and global aviation radiation monitoring. The closure occurred just as a S2 radiation storm was in progress with an average dose rate of 20 μSv h -1. We estimate that during the radiation event period, one-half million passengers were flying in the affected zone and, of this population, four would have received sufficient dose to contract fatal cancer in their lifetimes. The radiation environment can be treated like any other risk-prone weather event, e.g., rain, snow, icing, clear air turbulence, convective weather, or volcanic ash, and should be made available to flight crews in a timely way across the entire air traffic management system. The shutdown highlighted the need for active operational monitoring of the global radiation environment. Aviation radiation risk mitigation steps are simple and straightforward, i.e., fly at a lower altitude and/or use a more equatorward route. Public tools and media methods are also needed from the space weather scientific and operational communities to provide this information in a timely and accessible manner to the flying public.
