摘要自1988年以来，联邦土地管理者在IMPROVE能见度监测网络下监测了29个I类地区（主要是国家公园和荒野地区）和华盛顿的能见度和细颗粒物浓度。本文对1988 ~ 1996年9年期间第10次（最佳能见度日）、第50次（平均能见度日）和第90次（最差能见度日）连续三年的重建能见度和细颗粒物的趋势进行了评估。这些地点的数据显示了由于实施各种减排战略而产生的空气质量和能见度的区域趋势。
ABSTRACT Under the IMPROVE visibility monitoring network, federal land managers have monitored visibility and fine particle concentrations at 29 Class I area sites (mostly national parks and wilderness areas) and Washington, DC since 1988. This paper evaluates trends in reconstructed visibility and fine particles for the 10th (best visibility days), 50th (average visibility days), and 90th (worst visibility days) percentiles over the nine-year period from 1988-96. Data from these sites provides an indication of regional trends in air quality and visibility resulting from implementation of various emission reduction strategies.
