Hourly Data Reports

This page shows reports of data and averaging calculations for each hourly map for the last 24 hours.

Methodology:

CRN and METAR data for the closest match METAR hourly reporting station is acquired from the NOAAport satellite feed. Because of processing delays due to uplink, ingestion, quality control at the National Climatic Data Center (NCDC) and further delays in processing, uplink to NOAAport at Wallops Island, and then reception at our offices, the CRN data typically runs 1 hour or more behind the METAR data, which is reported hourly for the aviation network almost instantaneously.

The challenge for this project was to get these two asynchronous data sources synchronized. Currently every effort is made to get the two data sources synchronized and plotted on the same map about one hour and fifteen minutes behind real time. For the most part, all CRN and METAR stations have reported by this time

Below is a sample line of data for a CRN station. Left to right is:

Station ID, State_StationName, Date(YYYYMMDD_time, temperature in Celsius

63869, AL_Fairhope_3_NE, 20130207_2100, 22.3

Below is a sample line of data for a METAR station. Left to right is:

NOTE: NOAA rounds METAR data to nearest whole degree
