)A data frame with Oklahoma Mesonet data. See below for a list of variables including column ID, name, unit and description:
| ID | Name | Unit | Description |
| PRES | Station Atmospheric Pressure | kPa | 5-minute averaged atmospheric pressure. |
| RAIN | Precipitation | millimeters | Liquid precipitation accumulation since previous 5-min record. 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. |
a character vector of four-digit station identifiers for the Mesonet stations from which to download data
the first date for which to download data specified in Central Standard Time (i.e. "America/Costa_Rica") zone as a Date or POSIXt object or a string with the format YYYY-MM-DD, where YYYY is the four-digit year, MM is the two-digit numeric month and DD is the two-digit day of month
the final date for which to download data specified in Central Standard Time (i.e. "America/Costa_Rica") zone as a Date or POSIXt object or a string with the format YYYY-MM-DD, where YYYY is the four-digit year, MM is the two-digit numeric month and DD is the two-digit day of month
the root url from which to download MTS files (see mnet_root_url)
a data frame with site and soil information for each Oklahoma Mesonet station as returned by mnet_site_info. If NULL, mnet_site_info will be used to download this information internally
a character string providing a path to the local Mesonet file cache. If NULL, the function will search for the local file cache and if not found will prompt the user to create one.
whether or not to ask about creating a local Mesonet file cache
whether to suppress output to terminal (TRUE) or allow output to terminal (FALSE)
