• Middle Frequency Radar Measurements: Dynamics and Ionisation in the...

  Antarctica New Zealand

  Our studies investigate the Antarctic middle atmosphere’s response to natural and man-made factors which change climate. The dynamical processes of this region are significant in controlling the circulation at lower altitudes, including the stratospheric ozone layer. The feedbacks in the atmosphere, couple this change to climate change at the surface. The...

• Snowfall and Vertical Wind Measurements from Microrain Radar Systems, Ross...

  Antarctica New Zealand

  The microrain radar system (MRR2) is a compact 24.23GHz FM-CW which measures accurate estimates of snowfall, the size distribution of snow and the fall velocity of hydrometeors. Rain rates and the characteristic fall velocity are derived. See MRR2 specifications: https://metek.de/product/mrr-2/

• Microplastic Concentration in Snow Samples from Ross Island, Antarctica, 2019

  Antarctica New Zealand

  We collected a total of 19 samples were collected with 6 from locations near research stations and 13 from remote locations with minimal human disturbance across the Ross Island region of Antarctica. Samples were collected using a stainless-steel scoop and stainless-steel funnel to fill each 500 mL bottle with snow from the top 2 cm of the surface....
