Boulder Environmental Sciences and Technology (BEST) is involved in microwave remote sensing, and particularly in microwave radiometer development. Boulder Environmental Sciences and Technology (BEST) is developing several new radiometers for environmental monitoring: a Profiling Radiometer for Atmospheric and Cloud Observation ( PRACO), a Marine Profiling Radiometer ( MPR), and an Autonomous Profiling Radiometer ( APR). The instruments use novel design approaches that aim to remove the user completely from supervision and allow all-weather operation, data collection, and retrievals.The firm contends its instruments are lightweight, low-power, volume while very robust and flexible to customer needs. The firm seeks to provide customers with the reliable measurements of environmental variables they desire while aiming for an economical instrument, not only with respect to initial costs, but also to operational expenses.
