Droplet Measurement Technologies (DMT)

Cloud and Aerosol Instrument for Climate models & radiative forcing industry - Monitoring and Testing

In 1996, the first Intergovernmental Panel on Climate Change (IPCC) issued a report that underscored how aerosols and clouds impact radiative fluxes and modulate climate. Their first report and all subsequent reports every seven years have emphasized how the level of scientific understanding (LOSU) remains low. This major gap in our understanding of how aerosols and clouds alter climate continues to drive the need for more widespread and accurate measurements, especially of black carbon (BC) aerosols that contribute to climate warming and clouds that cool the climate.


The source and types of aerosols that form clouds remains a major puzzle. The Droplet CCN 100/200 and SPIN instruments provide answers to this puzzle by measuring cloud condensation nuclei (CCN) that become water droplets and ice nuclei (IN) that become ice crystals. Using Droplet’s SP2 and PAX instruments, climate scientists can study light absorbing BC that seriously warms the climate. And our BCP instrument enables Airbus A-330/340 commercial airliners to measure the impact of cirrus clouds on climate. Finally, every one of Droplet’s cloud spectrometers measure cloud properties that are critical to validating and tuning climate models.
