WCM water content for ACE-ENA
Abstract
The WCM-2000, manufactured by Science Engineering Associates (SEA), is a multi-element water content measuring system that measures both liquid water content (LWC) and total water content (TWC), allowing the inference of ice water content (IWC). The TWC is measured by a scoop-shaped sensor that collects both liquid and ice phase hydrometeors. The WCM-2000 also has two heated wire elements that are exposed directly to the airstream and a reference or compensation element that is exposed to the airflow but not the condensed water. The two heated wires measure the LWC for different size droplets and are sized to match the Johnson-Williams (JW) (021 Wire) LWC probe (0.5 mm; Neel 1955) and the King (083 Wire) probe (2 mm; King et al. 1978). The WCM-2000 is calibrated according to the manufacturer instructions, which involve a dedicated test flight in cloud-free air. Each flight is also corrected for zero-offset bias using clear-air measurements
