# Local Climatological Data (LCD)

The Local Climatological Data Version 2 (LCDv2) summaries provide a monthly synopses of climatic values for individual weather stations. LCDv2 supersedes the original LCD (v1) product, and contains identical data plus additional elements and stations. LCDv2 includes surface observations from the U.S., including Automated Surface Observing System (ASOS) and Automated Weather Observing System (AWOS) stations and international stations courtesy of the U.S. Air Force. 

Climatic measurements and summaries include hourly, daily, and monthly temperature, dew point, humidity, winds, sky condition, weather type, atmospheric pressure and more. Sub-daily and daily observations are sourced from the Global Historical Climatology Network hourly (GHCNh) and daily (GHCNd) products. The original LCD (v1) data values were represented in standard U.S. units and derived from the Integrated Surface Data (ISD) dataset which was sunsetted in 2023.
