Retrieve Oklahoma Mesonet subdaily data

Description

Retrieves data from the Oklahoma Mesonet for a given set of station identifiers and date range

Usage

mnet_retrieve(
  stid,
  start_date = NULL,
  end_date = NULL,
  root_url = mnet_root_url(),
  site_info = NULL,
  file_cache = NULL,
  ask = !silent,
  silent = FALSE
)

Arguments

stid

a character vector of four-digit station identifiers for the Mesonet stations from which to download data

start_date

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

end_date

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

root_url

the root url from which to download MTS files (see mnet_root_url)

site_info

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

file_cache

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.

ask

whether or not to ask about creating a local Mesonet file cache

silent

whether to suppress output to terminal (TRUE) or allow output to terminal (FALSE)

Value

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.
