Siting the DataRAM

The DataRAM should be placed at least 3 feet off the ground and away from obstructions (such as trees or buildings) that may influence airflow. It should be in an area where it will not be influenced by road dust, industrial pollutants, or other sources of particulate that could increase its readings.

The DataRAM should usually be sited several miles downwind of the burn in areas of greatest interest, such as communities or protected areas. The best use for the DataRAM is to determine whether the local particulate concentration is relatively high or low, and whether concentrations are going up or down. Acquire ambient background particulate concentrations before the burn to determine clean background conditions. If the instrument is to be left unattended, place it in the weather-resistant shelter. Be careful to insert the uncapped inlet port through the hole in the shelter. Once the DataRAM is in the shelter, place the heater, 2.5-micrometer cut-point device, and omnidirectional inlet on the DataRAM inlet port. The DataRAM power charger and power strip can fit inside the cover behind the instrument.

The DataRAM is sited in an open field for collecting smoke data.
