GCIP/ESOP-96: NCDC SAO Specials Dataset. Version 1.0

This dataset contains only the GCIP/ESOP-96 National Climatic Data Center (NCDC) Surface Aviation Observation (SAO) "Special" observation surface data for the ESOP-96 domain. These are observations that are reported at off-hour times and report significant changes in conditions from the previous hourly reports. These reports can include all of the information shown in hourly SAOs, but more typically, report only portions of the data. A complete listing of the requirements to issue a "special SAO" are included in the Federal Meteorological Handbook No. 1 (1988).

本数据集仅包含适用于ESOP-96区域的GCIP/ESOP-96项目下国家气候数据中心（National Climatic Data Center, NCDC）的地面航空观测（Surface Aviation Observation, SAO）“特殊”观测地面数据。此类观测均为非整点时段上报的观测，且相较于前一次整点观测报告，存在气象条件的显著变化。这类报告可涵盖整点SAO观测包含的全部信息，但通常仅会上报部分观测数据。发布“特殊SAO”观测的完整要求详见《联邦气象手册第1号（1988版）》。
