Climate Reference Network (CRN) Data
DescriptionThe The U.S. Climate Reference Network (USCRN) is a network of climate stations developed by the National Oceanic and Atmospheric Administration (NOAA). The USCRN's primary goal is to provide future long-term homogeneous temperature and precipitation observations that can be coupled to long-term historical observations for the detection and attribution of present and future climate change.
MADIS has been collecting data from 130 sites over the US including Alaska and Hawaii since April 16, 2010. The data is NOAA Port data received via the SBN.
Geographic CoverageCONUS, Alaska, and Hawaii.
Data ScheduleAll stations report five minute data once per hour and are available between 5 minnutes and 25 minutes after the top of the hour.
MADIS stores the data starting at the top of the hour and ending 59 minutes after the hour (e.g., the 0000 file covers 0000 - 0059).
Data that arrive after 2 hours following the time of the observation are processed in a "data recovery" mode, where once a day batch processing is performed to reprocess data that are 35 days, 7 days, and 1 day old. These data are available with all communications methods supported by MADIS except for ldm.
VolumeTypical daily volume for all MADIS datasets can be seen here.
RestrictionsNo restrictions. All observations are publicly accessible.
