Data Source 1

GLOBE Data Set Maximum Air Temperature

The daily Maximum Air Temperature was measured in accordance with GLOBE 's Maximum, Minimum, and Current Temperature Protocol. The U-shaped Maximum-Minimum Thermometer is kept in a white, well-ventilated housing to prevent it from being directly heated by the sun. The thermometer housing is kept sufficiently away from buildings and trees to avoid their impact. GLOBE protocol calls for the calibration of the thermometer to be checked regularly, and minimally to be checked once every three months.

Geospatial Coverage

GLOBE data exists for schools that are scattered across much of Earth. (Bounding Box: W = -180.0 degrees; E = +180.0 degrees; S = -90.0 degrees; N = + 90.0 degrees)

The two greatest concentrations of data exist in the United States (Bounding Box: W = -177.1 degrees; E = -61.48 degrees; S = +13.71 degrees; N = +76.63 degrees) and in Europe. (Bounding Box: W = -30.0 degrees; E = 50.0 degrees; S = +35.0 degrees; N = +70.0 degrees)

GLOBE Data Sets Soil Moisture at 10 cm and 90 cm

The water content of the soil is measured in terms of weight of water per gram of soil. It is determined using a sensor that measures the electrical conductivity of the water that enters a ceramic block from the surrounding soil. The sensor is placed at various depths below the surface of the ground (in this Chapter, at 10 cm and 90 cm), with wire leads running from the sensor to above ground level. Students attach a soil moisture meter to the wire leads to collect the data.

GLOBE Data Set Rainfall

Rainfall is measured using a rain gauge that is carefully positioned to collect accurate data. Schools participating in the GLOBE Program are encouraged to check and record rainfall daily, but for times when this is not possible, rain that collects for up to seven days can be reported as a total. While daily readings produce the most accurate information, scientists are interested in knowing the total amount of rainfall that an area receives.
