Although operations at the Polar Environment Atmospheric Research Laboratory (PEARL) nearby Eureka on Ellesmere Island (80 degrees North) have lately been paused, there is renewed interest in the site for astrophysical observations. I will briefly review known PEARL site conditions, and describe the status of a planned compact instrument for characterization of seeing near the ground, of...
I will report the progress and the status of the Greenland Telescope in Thule, Greenland. The telescope was commissioned in the spring of 2018, and it had since participated in the global VLBI observation campaign in millimeter and submillimeter wavelengths. The GLT has been a partner station in the Even Horizon Telescope since 2018 for the 230 GHz VLBI observation. In 2021, we have also...
At the University of New South Wales we are designing a wind turbine for the conditions found at China's Kunlun Station at Dome A in Antarctica. While Dome A is the least windy place on Earth, renewable energy from the wind is still possible and has many advantages over the diesel engines that are typically used: for example, wind energy reduces the need to transport and store fuel while...
A neutron monitor is a large ground-based detector responding to the flux of cosmic ray particles in space by measuring atmospheric secondary neutrons. Any ground-based detector is sensitive to cosmic rays from a certain range of directions in space. In particular, a particle arriving from a specific sky direction with a specific rigidity (momentum per unit charge) was necessarily moving in a...
