Soil Moisture Active/Passive SMAP, standing for Soil Moisture Active/Passive, is a NASA Environmental Research Satellite that combines a radar and radiometric instrument to measure land surface and soil moisture on a global scale at a very quick revisit rate to deliver data valuable in the understanding of Earth’s water, energy and carbon cycles, as well as valuable information for the improvement of weather and climate forecasting, flood prediction and drought monitoring.
Set for a three-year primary mission, the 944-Kilogram spacecraft will use a giant rotating reflector antenna to make its radar and radiometric measurements from a 685-Kilometer orbit. The SMAP mission and spacecraft are being developed and operated at the Jet Propulsion Laboratory with assistance from NASA’s Goddard Spaceflight Center. SMAP: Why It Matters. There are several disciplines that will benefit from SMAP’s measurements.
SMAP will help: Monitor Drought Because SMAP monitors soil moisture and provides critical information for drought early warning. In fact, a deficit in the amount of moisture in the soil defines agricultural drought. SMAP's measurements will come into play because researchers forecast a threefold increase in drought frequency in many regions of the world by the end of the 21st Century. EL DIAFRAGMA XXIV.
