Two sounding rocket payloads were launched from Andøya Space Centre (69.29 N, 16.02 E) during the summer of 2016 within the MAXIDUSTY campaign. Their payloads contained instrumentation aimed at investigating the characteristics of nanoscale aerosols in the upper summer mesosphere, and the role of these particles in phenomena like noctilucent clouds and polar mesospheric summer echoes (PMSE). The mesopause region, situated between $\sim 80$ and 90 km, contain a variety of different particle types such as ice particles, meteoric smoke particles (MSPs) and hybrids of these. The role of such particles in a number of processes in the mesopause and further down in the atmosphere is not well understood. This work aims to close some of the gaps in our current understanding mainly by using aerosol detectors of the Faraday cup type. For this purpose, we have developed new observational techniques using such probes, which makes it possible to obtain information on intrinsic particle properties such as charge state, size and number density of both ice and MSPs. The configuration and technical capabilities of the probes on MAXIDUSTY also allows for observation of spatial structures in the dusty plasma down to scales of $\sim 10$ cm. Notably, we are able to calculate the size distribution and charge state of ice particles on scales well below 1 metre. With the impact probe MUDD, we are able to infer the size distribution and volume content of MSPs embedded in larger ice particles. We moreover present the first observations of mesospheric clouds situated well below the summer mesopause, at altitudes between $66$ and 78 km, which implies a significant updraft in this region. From a thorough investigation into spatial fluctuations on different length scales, we find that the aerosol-electron coupling is changing throughout a cloud system and not strictly anti-correlated. We also find that a simple relationship between PMSE and dusty plasma parameters is not possible to obtain from MAXIDUSTY measurements. To sonderaketter ble skutt opp fra Andøya Space Center (69.29 N, 16.02 E) under MAXIDUSTY-kampanjen sommeren 2016. Deres nyttelaster inneholdt instrumentering med mål om å undersøke karakteristika av nanoskala aerosoler i den øvre mesosfære, og rollen til disse partiklene i fenomener som nattlysende skyer og polare sommer-mesosfæriske ekko (PMSE). Mesopausen, lokalisert i høydeområdet $\sim 80$ til 90 km, inneholder mange forskjellige partikkeltyper som ispartikler, meteoriske røykpartikler (MSP) og hybrider av disse. Rollen til slike partikler i mange prosesser i den øvre atmosfære er ikke godt forstått. Dette arbeidet sikter på å besvare noen av de ubesvarte spørsmål om mesosfæriske aerosoler ved å hovedsaklig bruke såkalte Faraday-bøtter. Vi har utviklet nye observasjonsteknikker for slike prober som gjør det mulig å få informasjon om egenskaper som ladning, størrelse og nummertetthet til både is og MSP. Konfigurasjonen og de tekniske egenskapene til probene på MAXIDUSTY-nyttelastene gjør det også mulig å måle romlige fluktuasjoner i støvplasmaet på skalaer ned til $\sim 10$ cm. Spesielt nevnes at vi har målt størrelsesfordelingen og ladningstilstanden til ispartikler på skalaer vel under 1 meter. Med proben MUDD kan vi estimere strørrelsesfordelingen til MSPer som er innevokst i større ispartikler. Vi presenterer den første observasjonen av mesosfæriske skyer vel under mesopausehøyder i sommermesosfæren -- mellom 66 og 78 km. Dette impliserer en signifikant oppdrift i denne regionen. Fra en undersøkelse av fluktuasjoner på forskjellige lengdeskalaer, finner vi at aerosol-elektron-koplingen endrer seg gjennom et skylag og ikke strengt anti-korrelert. Vi finner også at et enkelt forhold mellom PMSE og støvplasmaparametere ikke er mulig å finne fra målingene gjort under MAXIDUSTY. |
