Methods used in producing this dataset:
Auto transect measuring climate variables
Davis Instruments hardware was mounted, read, and recorded in the vehicle used in all transects in the following manner: 1) the temperature and relative humidity module was placed outside of the vehicle in the front and center. The sensor was placed suspended ~1 cm above a 20 cm square strip of Plexiglas, which had been painted white to keep it from absorbing heat. The Plexiglas, in turn was located on top of a 10 cm high radio mount antenna, originally intended for a CB radio device. This radio mount was magnetic on the bottom, allowing it to adhere to the metal surface of the vehicle solidly, but also allowing the sensor to be a non-permanent structure on the vehicle; 2) the temperature and relative humidity sensor was attached to a Davis Sensor Interface Module Standard Model 7978, via a cable that ran through an open passenger window to the module on the passenger seat; 3) a Health EnviroMonitor Product no. 7475 (the datalogger and digital readout) was connected to the Interface Module via an Envirolink Isolator on one end, and finally on the other end was connected to a home computer at download time via a serial port.
