Subject: Removal of Surface Observations from NWS API Website,
 Effective April 24, 2024

On April 24, 2024, the National Centers for Environmental Prediction
(NCEP) Central Operations (NCO) turned off a subset of surface
observation
data on the NWS API Website, https://api.weather.gov.

To prioritize the timeliness of watches, warnings, and advisories,
surface
observational data served from the NWS API observation endpoint will
be
limited to primarily CONUS locations.

The affected endpoint:
https://api.weather.gov/stations/SITEID/observations
Where SITEID is the identifier of the observing station.

To see a map of what locations will still be available, or to see a
list
of what stations are no longer available:

For an alternate method to access the removed data sets please use:
 https://madis-data.ncep.noaa.gov


The Office of Dissemination would like feedback on the impacts of
permanently discontinuing these data sets from the NWS API. Please
provide
feedback to:
 ryan.l.solomon@noaa.gov

For operational issues with the NWS API, or questions about the
proposed
change, please contact:
