US:station:::Download data from the Unavco web services.

The “database” option defines different return data.

met:

Returns hourly meteorological data for the specified station and
timeframe.  Pressure, temperature, humidity, wind speed and
direction are provided as averages of all the samples taken per
hour. Rain and hail are totals for the hour. The sample count is
the number of samples taken per hour.

Stations are configured to sample either at 1 minute or 5 minute
intervals and the user can determine which by looking at the
sample counts over several hours to see if they approach 12 or
60.

Returns: sample timestamp, pressure (mbar), temperature (degree
C), relative humidity(per cent), wind direction(degrees), wind
speed(m/s), rain(0.1mm), hail(hits), sample count

pore_temperature:

Pore pressure and temperature readings are collected by pore
pressure sensors co-located with borehole strainmeters. Tilt data
is collected by shallow borehole tiltmeters co-located with
borehole strainmeters and seismic stations.

Get pore temperature for the specified stations and time range.

Returns: sample time, temperature(degree C)

pore_pressure:

Pore pressure and temperature readings are collected by pore
pressure sensors co-located with borehole strainmeters. Tilt data
is collected by shallow borehole tiltmeters co-located with
borehole strainmeters and seismic stations.

Get pore pressure for the specified stations and time range.

Returns: sample time, pressure (hPa)

tilt:

Get tilt data for specified stations and time range.

Returns: DateTime, X-axis tilt (microRadians), Y-axis tilt
(microRadians), Temperature (degree C), Voltage(v)

strain:

Geodetic strain data is collected by four-component deep borehole
tensor strainmeters that record transient deformation signals
yielding information about the physical properties of the
surrounding rock.

Borehole strainmeters measure very small changes in the dimension
of a borehole at depths ranging from 100m to 250m. The Plate
Boundary Observatory uses a instrument developed and constructed
by GTSM Technologies which measure the change in borehole
diameter along three azimuths separated by 120 degrees
perpendicular to the borehole.

Get borehole strain data for the borehole strainmeter station
identified.  This data is low rate, 5 minute sample, level
2 uncorrected and corrected strain data. Corrected values are the
uncorrected strain minus the effects of the tidal signal and
barometric pressure.

Returns: DateTime, Gauge 0 uncorrected microstrain, Gauge
1 corrected microstrain, Gauge 1 uncorrected microstrain, Gauge
1 corrected microstrain, Gauge 2 microstrain, Gauge 2 corrected
microstrain, Gauge 3 microstrain, Gauge 3 corrected microstrain,
Eee+Enn uncorrected microstrain, Eee+Enn corrected microstrain,
Eee-Enn uncorrected microstrain, Eee-Enn corrected microstrain,
2Ene uncorrected microstrain, 2Ene corrected microstrain.
