Abstract [sv]

“Rocket  deployed  Atmospheric  probes  conducting  Independent  measurements  in  NorthernSweden” (RAIN) är ett projekt där teamet utvecklat och byggt ett experiment för provtagning av aerosolpartiklar  i  mellersta  atmosfären.    Experimentet  skjuts  upp  med  en  sondraket  ifrån Esrange i Kiruna i slutet av Mars 2012. Det består av två mätsonder som monteras i raketcylindern, skjuts ut från denna och faller fritt från ca 80 km höjd. Under fallet genom atmosfären samlar mätsonderna in prover vid olika höjder. Proverna kommer efter experimentet att analyseras i svepelektronmikroskop (SEM). Atmosfäriska aerosolpartiklar spelar en viktig roll i molnbildning på olika höjder och påverkar både klimatet och miljön på jorden. Provtagning av dessa på hög höjd är dock ett problem och ingen bra teknik för detta finns idag.Eftersom uppsatsen skrivs inom ramarna för ett examensarbete på programmet Civilingenjör & Lärare är den tvådelad, en teknisk del och en pedagogisk del. Den tekniska delen beskriver arbetet med testerna av provtagning av aerosolpartiklar vid markytan samt SEM analysen av dessa prover. Den pedagogiska delen beskriver arbetet med att sprida intresse för naturkunskap och teknik genom att utföra skolbesök och presentera projektet RAIN.

Abstract [en]

“Rocket  deployed  Atmospheric  probes  conducting  Independent  measurements  in  NorthernSweden” (RAIN) is a project where the team developed and constructed an experiment for multipoint sampling of aerosol particles in the middle atmosphere. The experiment is launched with a sounding rocket from Esrange in Kiruna March 2012. It consists of two probes which are mounted in the rocket cylinder. They will be ejected from this and fall from about 80 km height. During the fall through the atmosphere the probes collect samples on different heights. The post experiment analysis is done with a scanning electron microscope (SEM). Atmospheric aerosol particles play an important part in cloud formation and have impact on both climate and environment on earth. Sample-taking of them in high altitudes is a problem though and there exists no good technique for this today.This Master thesis has two parts, one technical and one pedagogical, since it is written within the frames of the program Master of Science in Engineering and of Education. The technical part covers the test of aerosol particle collection at ground level and the post-test SEM analysis of this. The pedagogical part describes the work with spreading interest for science and technology by school visits presenting project RAIN.
