Accurate and fast routine temperature measurements in this region will help furtherour understanding of the above-canopy internal boundary layer structure and the spatial variability of UrbanBoundary Layers (Barlow 2014). Data implications include improving forecasting of Urban Heat Island eventsand urban weather, improving air pollution modelling and informing sustainable urban planning. Other methodsof making such measurements routinely, such as using manned aircraft or Unmanned Aerial Vehicles (UAVs), canbe prohibitively expensive or require onerous permissions and logistics to achieve.A first-iteration prototype was carried initially by a trained White-tailed Eagle (Haliaeetus albicilla) and anImperial Eagle (Aquila adalberti) to assess probe-mounting locations (back or tail mounted temperature sensor),other met sensors and the potential for data contamination due to heat generation by birds (Thomas et al. 2017).Other characterisation tests included car-mounted solar radiation shield tests, UAV-mounted tests for altimetertesting and field tests of temperature responses to solar-heated surface elements.We present results demonstrating that packages meet their specified target of measuring at least a 0.5 de-gree celcius change in temperature over each hundred metres of flight track, as well as accurately recordingtheir location and orientation using on-board GPS, 3-axis gyroscopes and accelerometers, and a pressure altitudesensor. The package has been miniaturised and carried by captive homing pigeons (Columba livia) for initial testsprior to more widespread deployment later in 2018.1.
