1) Upper air pressure as measured by the anasphere, tethered to the Helekite. Flights were launched primarily at stations, therefore data is intermittent. Not to be confused with atmospheric pressure measured by the barometer aboard RVI. 2) Altitude of the Helekite during flights. Flights were launched primarily at stations, therefore data is intermittent. 3) Upper air temperature as measured by the anasphere, tethered to the Helekite. Flights were launched primarily at stations, therefore data is intermittent. Not to be confused with ambient or lab temperatures measured on RVI 4) Upper air relative humidity as measured by the anasphere, tethered to the Helekite. Flights were launched primarily at stations, therefore data is intermittent. Not to be confused with ambient or lab humidities measured on RVI and 5) Upper air wind speed as measured by the windsonde tethered to the Helekite. Flights were launched primarily at stations, therefore data is intermittent. Not to be confused with ambient wind speed measured by the wind vanes aboard RV Investigator.
