[/et_pb_text][et_pb_accordion use_border_color=”off” _builder_version=”3.0.106″][et_pb_accordion_item title=”AirTempF_Min” _builder_version=”3.0.106″]

AirTempF_Min is the minimum temperature recorded during the last 24 hours.

[/et_pb_accordion_item][et_pb_accordion_item title=”AirTempF_Max” _builder_version=”3.0.106″]

AirTempF_Max is the maximum temperature recorded during the last 24 hours.

AvgPartL is the particulate concentration measurement. Each of the 5 weather stations in the Borrego valley is measuring in either PM2.5, PM10, or TSP (Total Suspended Particulates) sharp-cut cyclone. Measurements are in ug/m3.

[/et_pb_accordion_item][et_pb_accordion_item title=”BattV_Min” _builder_version=”3.0.106″]

BattV_Min is the minimum battery voltage of the past 24 hours. We keep an eye on this number to make sure it doesn’t drop below 11 volts. The solar panels keep the batteries charged so there’s juice for measurements and communications during nights and cloudy days.

[/et_pb_accordion_item][et_pb_accordion_item title=”BP_mmHg” _builder_version=”3.0.106″]

BP_mmHg is the Barometric Pressure Sensor measurement measured in mmHg units

[/et_pb_accordion_item][et_pb_accordion_item title=”PTemp_C” _builder_version=”3.0.106″]

PTemp_C is the panel temperature of the datalogger, not the outside ambient temperature.

[/et_pb_accordion_item][et_pb_accordion_item title=”Rain_mm_Tot” _builder_version=”3.0.106″]

Rain_mm_Tot is the total precipitation measured in mm. One inch of rain equals 25.4 mm.

[/et_pb_accordion_item][et_pb_accordion_item title=”Rain_in_Tot” _builder_version=”3.0.106″]

Rain_in_Tot is the total precipitation measured in inches. One inch of rain equals 25.4 mm.

[/et_pb_accordion_item][et_pb_accordion_item title=”Soil volumetric water content” _builder_version=”3.0.106″]

Soil volumetric water content reflectometers measure volumetric water content (VWC) of soils or other porous media. The water content information is derived from the probe sensitivity to the dielectric constant of the medium surrounding the probe rods.

[/et_pb_accordion_item][et_pb_accordion_item title=”SlrkW” _builder_version=”3.0.106″]

SlrkW is the Solar radiation received in KiloWatts. The SI unit of irradiance is watt per square meter (W/m2)

[/et_pb_accordion_item][et_pb_accordion_item title=”SlrkW_Avg” _builder_version=”3.0.106″]

SlrkW_Avg is the average Solar radiation received in KiloWatts. The Solar Irradiation unit of irradiance is watt per square meter (W/m2) Insolation is the power received on Earth per unit area on a horizontal surface. It depends on the height of the Sun above the horizon.[1]

[/et_pb_accordion_item][et_pb_accordion_item title=”SlrkW_Max” _builder_version=”3.0.106″]

SlrkW_Max is the maximum Solar radiation received in KiloWatts. The Solar Irradiation unit of irradiance is watt per square meter (W/m2) Insolation is the power received on Earth per unit area on a horizontal surface. It depends on the height of the Sun above the horizon.[1]

[/et_pb_accordion_item][et_pb_accordion_item title=”SlrMJ_Tot” _builder_version=”3.0.106″]

SlrMJ_Tot is the total Solar Irradiation unit of irradiance is megajoule watt per square meter (MJ/m2)

[/et_pb_accordion_item][et_pb_accordion_item title=”TCAV_1_Avg” _builder_version=”3.0.106″]

TCAV_1_Avg and TCAV_2_Avg (Averaging Soil Thermocouple Probe) measures the averages in soil temperature between 4 temperature probes buried underneath the soil. These temperature probes are buried at a depth of 2 cm and 6 cm, and record the temperature in degrees Celcius.There are a total of two sets of these probes, or 8 probes buried per weather station.

[/et_pb_accordion_item][et_pb_accordion_item title=”WS_mh_Max” _builder_version=”3.0.106″]

WS_mh_Max is the maximum wind speed recorded in miles per hour. Typically this is the maximum wind gust recorded that previous hour.
