The Campaign
The Soil Moisture Experiment (SMEX) was a field investigation that studied soil moisture across North America to support the Aqua Advanced Microwave Scanning Radiometer (AMSR) and other terrestrial hydrology satellite missions. SMEX consisted of four deployments during the boreal summer of 2002-2005 across Iowa, Oklahoma, Alabama, Georgia, Arizona, and Mexico. Multiple airborne remote sensors such as the Polarimetric Scanning Radiometer (PSR), Two-Dimensional Electronically Scanning Thinned-Array Radiometer (2D-STAR), and the Airborne Synthetic Aperture Radar (AIRSAR) collected measurements of soil moisture. Ground-based observations were also collected through various networks and flux towers. SMEX was a joint effort between NASA and the United States Department of Agriculture (USDA).

Rain gauges are ground-based instruments that provide in situ measurements of liquid precipitation amounts over a set time. There are multiple types of rain gauges that each collect and record data differently such as the tipping bucket rain gauge and weighing precipitation gauge. Rain gauges can be deployed in various locations due to their relatively small size and easy set-up and are typically colocated with other precipitation instruments such as disdrometers to provide more details about precipitation being collected such as precipitation rate and size distribution.

Stream gauges are ground-based sensors that provide in situ measurements of the stage or height of rivers and streams. The stream flow or discharge of the river can be derived from the stage measurements. Stream gauges can provide continuous measurements and are useful for monitoring flooding potential and water supply. The United States Geological Survey (USGS) maintains and operates a network of over 10,000 stream gauges across the United States to aid with flood forecasting and water management.

A pyrometer is a remote-sensing infrared thermometer that measures the temperature of distant objects. It determines the temperature of an object by detecting its thermal radiation. It can be deployed on aircraft, ground, or water-based platforms for surface and sea surface temperature observations. For atmospheric studies, the pyrometer typically operates in the 9.6 to 11.5 µm spectral range and has a temperature range of -25 to 200 degrees Celsius. Pyrometers have a typical response time of 5 ms to 600 s.

Soil moisture probes are in situ ground-based sensors used to measure soil water content. The most common type of soil moisture probes used for scientific research use dielectric permittivity techniques such as capacitance sensors or time-domain reflectometry sensors. These types of probes measure the charge-storage capacity of the soil to determine the soil moisture content. They typically operate at frequencies around 50 MHz and above to reduce sensitivity to salinity. Soil moisture probes provide continuous measurements and are relatively easy to deploy.

The Airborne Synthetic Aperture Radar (AIRSAR) was an airborne P-, L-, and C-band radar system developed by the Jet Propulsion Laboratory (JPL). It was able to penetrate through clouds and operate at night to provide measurements of radar backscatter. It also could penetrate forest canopy, dry snow cover, and sand in two of its imaging modes. AIRSAR operated across three frequencies: 0.45 GHz, 1.26 GHz, and 5.31 GHz. It had a horizontal resolution of 10 m and a swath width of around 10-15 km at a flight altitude of 8,000 m. AIRSAR is now retired and flew its last mission in 2004.

The Passive Active L- and S-band Sensor (PALS) is a combined airborne polarimetric radiometer and radar developed by NASA’s Jet Propulsion Laboratory (JPL). It was designed to evaluate the benefits of combining remote passive and active sensors for ocean salinity and soil moisture measurements. Both the radiometer and radar within PALS operate across the L- (1.41 GHz, 1.26 GHz) and S-band (2.69 GHz, 3.15 GHz) frequencies to measure brightness temperature and radar backscatter of ocean salinity and soil moisture. PALS has a spatial resolution ranging from 600 to 1500 m depending on the altitude of the aircraft. PALS can be equipped on many different aircraft due to its design and is typically used for validation of Aquarius and SMAP satellite observations.

Radiosondes are a balloon-borne instrument package used to collect profile measurements of pressure, temperature, humidity, and winds. These sensors are connected to a radio transmitter that sends the measurements to a ground receiver typically operating in the 400-406 MHz range. They typically provide measurements at 1-6 seconds, depending on the type and manufacturer of the radiosonde. Radiosondes are used for weather forecasting, ground truth satellite data, atmospheric research, and input for weather prediction models.
