Value

A data frame with Oklahoma Mesonet data. See mnet_variable_definition() or the table below for the ID, variable name, unit and description for each column.

ID	Name	Unit	Description
PRES	Station Atmospheric Pressure	kPa	5-minute averaged atmospheric pressure.
RAIN	Precipitation	millimeters	Liquid precipitation accumulation since 0000 UTC. Frozen precipitation cannot be recorded until it melts; therefore, precipitation from snow may not be recorded until several days after the snow event.
RELH	Relative Humidity	percent	5-minute averaged relative humidity at 1.5m.
SRAD	Solar Radiation	watts per square meter	5-minute averaged downwelling global solar radiation.
STID	Station ID		Station ID
STNM	Station Number		Station Number
TA9M	Air Temperature at 9m	degrees Celsius	5-minute averaged air temperature at 9m
TAIR	Air Temperature	degrees Celsius	5-minute averaged air temperature at 1.5m.
TB05	Temperature Under Bare Soil at 5cm	degrees Celsius	15-minute averaged temperature under bare soil at 5cm. This variable is only available prior to December 1, 2013.
TB10	Temperature Under Bare Soil at 10cm	degrees Celsius	15-minute averaged temperature under bare soil at 10cm.
TIME	Time	minutes after base time	Minutes after base time (typically 0000 UTC)
TR05	Soil Moisture Calibrated Delta-T at 5cm	degrees Celsius	30-minute calibrated change in temperature of soil over time after a heat pulse is introduced. Used to calculate soil water potential, fractional water index, or volumetric water.
TR25	Soil Moisture Calibrated Delta-T at 25cm	degrees Celsius	30-minute calibrated change in temperature of soil over time after a heat pulse is introduced. Used to calculate soil water potential, fractional water index, or volumetric water.
TR60	Soil Moisture Calibrated Delta-T at 60cm	degrees Celsius	30-minute calibrated change in temperature of soil over time after a heat pulse is introduced. Used to calculate soil water potential, fractional water index, or volumetric water.
TR75	Soil Moisture Calibrated Delta-T at 75cm	degrees Celsius	30-minute calibrated change in temperature of soil over time after a heat pulse is introduced. Used to calculate soil water potential, fractional water index, or volumetric water.
TS05	Temperature Under Native Vegetation at 5cm	degrees Celsius	15-minute averaged temperature under native vegetation at 5cm.
TS10	Temperature Under Native Vegetation at 10cm	degrees Celsius	15-minute averaged temperature under native vegetation at 10cm.
TS25	Temperature Under Native Vegetation at 25cm	degrees Celsius	15-minute averaged temperature under native vegetation at 25cm. This variable is only available after and including December 1, 2013.
TS30	Temperature Under Native Vegetation at 30cm	degrees Celsius	15-minute averaged temperature under native vegetation at 30cm. This variable is only available prior to December 1, 2013.
TS45	Temperature Under Native Vegetation at 45cm	degrees Celsius	15-minute averaged temperature under native vegetation at 45cm.
TS60	Temperature Under Native Vegetation at 60cm	degrees Celsius	15-minute averaged temperature under native vegetation at 60cm. This variable is only available after and including December 1, 2013.
VW05	Volumetric soil water Under Native Vegetation at 5cm	cm^3^ cm^-3^	5-minute averaged volumetric soil water under native vegetation at 5cm.
VW25	Volumetric soil water Under Native Vegetation at 25cm	cm^3^ cm^-3^	5-minute averaged volumetric soil water under native vegetation at 25cm.
VW45	Volumetric soil water Under Native Vegetation at 45cm	cm^3^ cm^-3^	5-minute averaged volumetric soil water under native vegetation at 45cm.
WDIR	Wind Direction	degrees	5-minute averaged wind direction at 10m.
WDSD	Wind Direction Standard Deviation	degrees	Standard deviation of wind direction during the 5-minute interval.
WMAX	Maximum Wind Speed	meters per second	Highest 3-second wind speed at 10m sample.
WS2M	2m Wind Speed	meters per second	5-minute averaged wind speed at 2m
WSPD	Wind Speed	meters per second	5-minute averaged wind speed at 10m.
WSSD	Wind Speed Standard Deviation	meters per second	Standard deviation of wind speed during the 5-minute interval.
WVEC	Wind Vector	meters per second	5-minute averaged wind velocity (speed and direction accounted for) at 10m.
