Hydrosphere GLOBE Protocol eTraining Modules

The Hydrosphere is the water component of our planet, and includes liquid water, ice and vapor. Changing any part of the Earth system, such as the amount or type of vegetation in a region or from natural land cover to an impervious one, can affect the rest of the system, and water plays a role in many of these changes. Rain and snow capture aerosols from the air. Acidic water slowly dissolves rocks, placing dissolved solids in water. Dissolved or suspended impurities determine water's chemical composition. Water is a good solvent and participates in many of the chemical reactions that take place in the Earth system. Scientific measurement programs in many areas of the world cover only a few water bodies a few times during the year, so GLOBE students provide valuable data to help fill these gaps and improve our understanding of Earth's natural waters. Students and scientists investigate hydrology through the collection of data using measurement protocols and using instruments which meet certain specifications in order to ensure that data are comparable. The training slides in this section will introduce you to the measurement protocols for the various hydrosphere protocols in GLOBE. Hydrosphere Protocol eTraining Modules
