Notes
EISCAT experiment in support of three sounding rocket campaigns (ICI-5, CHI and C-REX), which are part of the Cusp Grand Challenge Initiative (Cusp GCI), a multi-country collaboration (Norway, US, UK, Japan) to combine several rocket experiments and other measurements to provide one of the most comprehensive cusp ionosphere measurements to date. See more information here: https://www.andoyaspace.no/the-grand-challenge-initiative/ CHI will be launched from Ny-Ålesund and deploy eight barium/strontium tracer clouds to obtain detailed in-situ plasma drift and neutral wind measurements in the cusp near Svalbard. The objective is to better understand the neutral upwelling that is now known to be common feature in the cusp and the electrodynamic drivers for the phenomenon. Key objectives are: 1) Measure the electric fields and electron densities and their spatial variations within the cusp region 2) Measure both the horizontal and vertical neutral flow components in the same region where the electric fields and electron densities are measured 3) Obtain high-resolution estimates of the Joule heating, including spatial and temporal variations, in order to assess the contribution of the heating in driving the local upwelling ICI-5 will be launched from Ny-Ålesund and make multi-point in-situ measurements of ionospheric irregularities in the cusp ionosphere. A key instrument is the multi-needle Langmuir Probe that has been developed at the University of Oslo. A total of 12 daughter payloads will be released from the mother payload in order to obtain temporal-spatial information ion ionospheric irregularities. Key objectives are: 1) Investigate the time/space variations of plasma irregularity regions using multi-point in-situ measurements 2) Quantify instability drivers in the cusp-polar cap ionosphere 3) Investigate the growth and decay rates of instabilities C-REX will be launched from Andøya Space Center and fly towards Svalbard, where it will release 24 bright, colorful and glowing clouds. The clouds will be photographed by observers in Svalbard and onboard a NASA aircraft. The images will be used to triangulate the position and motion of each cloud, in order to derive winds and electric fields in the cusp thermosphere. All three rocket campaigns involve observations from a wide range of ground- based instruments; the EISCAT Svalbard Radar, optical instruments (KHO, NYA), SuperDARN radars, and GNSS scintillation and TEC receivers. The EISCAT Svalbard Radar will use both antennae (42m field-aligned, and 32m). Depending on ionospheric conditions at the time, the 32m will either be operated in a scan mode or pointed along the rocket track (in a fixed direction). Potential experiment modes are taro, folke or steffe. Required measurements are electron density, electron/ion temperatures, and ion drifts.
