PFE METRIC 4: PFAC or. Representative on Hospital. Committee. The intent of this metric is that a hospital has a formal. relationship with patient and family advisors from the local. community who provide input and guidance from the patient. perspective on hospital operations, policies, procedures, and. quality improvement efforts.
Haze is traditionally an atmospheric phenomenon where dust, smoke and other dry particles obscure the clarity of the sky. The World Meteorological Organization manual of codes includes a classification of horizontal obscuration into categories of fog, ice fog, steam fog, mist, haze, smoke, volcanic ash, dust, sand and snow. Sources for haze particles include farming (ploughing in dry weather), traffic, industry, and wildfires.
Effects of Arctic haze on surface cloud radiative forcing. Authors. Abstract. From 4 years of observations from Barrow, Alaska, it is shown that the cloud radiative impact on the surface is a net warming effect between October and May and a net cooling in summer. During episodes of high surface haze aerosol concentrations and cloudy skies, both the net warming and net cooling are amplified, ranging from +12.2 Wm â2 in February to â11.8 Wm â2 in August.
