Meteorological Data from the Oklahoma MesonetworkEntry ID: OKLAHOMA_MESONET
The Oklahoma Mesonetwork is a network of over 110 automated environmental monitoring stations operated jointly by Oklahoma State University and The University of Oklahoma. At least one site is located in each of Oklahoma's 77 counties. The average spacing between stations is approximately 32 km. The network collects data at 5-minute intervals with 5-minute resolution, ... 24-hours per day. Data are recorded at each site and relayed to a base-station computer via radio telemetry.
The following parameters are measured: Air Temperature (1.5 and 9.0 meters), Relative Humidity (1.5 meters), Wind Speed/Direction (10 meters), Wind Speed (2 meters), Barometric Pressure (0.75 meters), Rainfall via tipping bucket (surface), Solar Radiation (1.8 meters), Soil Temperature bare soil (5 and 10 cm) and sod (5, 10, and 30 cm), and Soil Moisture (5, 25, and 60 cm).
The network was developed to adhere as closely to WMO guidelines as possible. Therefore, Mesonet acts as both a real-time observation network and a research-quality archive. Dataloggers can store up to 30 days of data, allowing for retrieval of data 'lost' during communications failures. The archive data set contains nearly 100% of possible observations since Mesonet was commissioned in March, 1994.
Data are available upon request to the Oklahoma Climatological Survey. The network was developed under a grant from the Oklahoma Department of Energy and is supported through a combination of state, federal, and private funding.

Quality The Mesonet's quality assurance system consists of 5 components: (1) Lab Calibration, (2) Automated Software, (3) Manual Inspection, (4) In-Field Comparisons, and (5) Routine Maintenance. During Lab Calibration, each sensor is tested or calibrated before deployment to a remote site. When a sensor reaches its rotation interval, it is returned from the field and re-calibrated. This provides an ... accurate calibration history for each sensor. The Mesonet's custom Automated Software provides an efficient means to sift through the nearly 1 million observations collected each day. Any observation that has failed an automated test is manually inspected by full-time Quality Assurance Meteorologists. The QA Meteorologists also employ numerous manual methods to inspect and quality assure the data. For In-Field Comparisons, reference sensors are taken to each remote station to test how the site's temperature, relative humidity, pressure, rainfall, and solar radiation sensors are performing. Lastly, for Routine Maintenance, each station is visited, at a minimum, each Spring, Summer, and Fall to clean/test sensors and to maintain site vegetation.
QA flags are stratified (0="good", 1="suspect", 2="warning", and 3="failure") so that users can decide the level of QA they prefer.
