SPIDER-1 measurements (LP, GPS, SMILE) inside an aurora
A series of CSV files containing some of the measurements performed by the SPIDER-1 sounding rocket inside an aurora. The rocket was launched at 21:09UT on February 2nd 2016 from Esrange (Kiruna, Sweden) and ejected 10 Free Falling Units (FFUs) inside a westward-traveling active aurora. Each FFU was equipped with a deployable Langmuir probe (LP) to measure the plasma properties (the electron density ne, the electron temperature Te, and the plasma potential Vp), as well as a 3-axis fluxgate magnetometer (SMILE) measuring the magnetic field and a positioning recorder (GPS). Usable data from two of the FFUs (FFU02 and FFU06) is presented, which was used in the JGR-Space Physics article named "Multi-point measurements of the plasma properties inside an aurora from the SPIDER sounding rocket." The data was collected by two of the SPIDER Free Falling Units (FFU02 and FFU06). It included: - Measurements from the Langmuir probe (LP, current measurements for each voltage bias steps) - Measurements from the 3-axis magnetometer (SMILE) - Processed data from the Langmuir probe, namely the electron density (ne), electron temperature (Te) and plasma potential (Vp). - GPS position of the two FFUs.
Information pertaining to earth sciences.
Refers to dynamic processess of the Earth's ionosphere and solar magnetosphere\ntriggered by solar events. The magnetosphere is the magnetic cavity surroundingthe earth, carved out of the passing solar wind by virtue of the geomagnetic\nfield, which prevents, or at least impedes, the direct entry of the solar wind\nplasma into the cavity. The ionosphere is the region of the earth's upper\natmosphere containing a small percentage of free electrons and ions produced byphotoionization of the constituents of the atmosphere by solar ultraviolet\nradiation at very short wavelengths (l.t.1000 angstroms). The ionosphere\nsignificantly influences radiowave propagation of frequencies less than about\n30 MHz.
A faint visual phenomenon associated with geomagnetic activity,\nwhich occurs mainly in the high-latitude night sky. Typical\nauroras are 100 to 250 km above the ground. The phenomenon\ncaused by collisions between charged particles, atoms, and ions\nin the Earth's ionosphere and upper atmosphere.
