Presentation Transcript

  1. Science applications for EISCAT-3D: possibilities for atmospheric research from the mesosphere down to the troposphere Evgenia Belova, Sheila Kirkwood Swedish Institute of Space Physics, Kiruna, Sweden

  2. From mesosphere… PMSE/PMWE research Polar Mesosphere Summer Echoes and Noctilucent Clouds, NLCs NLCs. Photo by P.Dalin PMSE with MST 50 MHz and EISCAT VHF radars

  3. SOFIE – Solar Occultation FOr Ice on the ÀIM satellite MARA –Moveable Atmospheric Radar for Antarctica Kirkwood et al., submitted to AnGeo PMSE VR ~ Ne Mice Now: Ne measurements are not possible during PMSE EISCAT_3D: common volume measurements PMSE from transmitting site and Ne from remote sites

  4. Polar Mesosphere Winter Echoes Vhor ~ 300-400 m/s Belova et al. 2005 Now: strength , spectral widths, vertical winds above ~65 km EISCAT_3D: horizontal winds, arrival angle (aspect sensitivity), 3D distribution over the whole beam The same set of parameters as ESRAD but for 60 cm length-scale plus extra. Lower altitudes 50-70 km capabilities to detect more scattering layers

  5. Down to the troposphere… Scatter of radar wave is on fluctuations of humidity, neutral temperature, Ne Novel applications for EISCAT_3D: • Fine-scale layering in the troposhere/lower stratosphere (up to 12-18 km) • Turbulent mixing • Wave propagation in the stratosphere Hocking, 1985

  6. Fine-scale layers in the troposphere/lower stratosphere ESRAD 50 MHz radar July 2009 Hooper et al., 2004 Temperature profiles/structure (both vertical and horizontal)

  7. Turbulent mixing associated with the tropopause fold:stratospheric air can be transported into the troposphere Rao et al. 2006

  8. GW propagation in the stratosphere

  9. Summary • Interferometric measurements for mesosphere; 3D-structure • Lower altitudes coverage with interferometric capabilities; 3D- structure • Raw data (I&Q) is required • Extra: Small moveable system (for field/expedition measurements)
