Galaxy Correction Upgrade in the Soil Moisture Active/Passive (SMAP) Microwave Radiometer Algorithm
IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018The SMAP mission was designed to measure soil moisture globally for quantifying the water and carbon cyclces. The Brightness Temperature (TB) measurement by the SMAP L-band radiometer over ocean is also used for Sea Surface Salinity (SSS) retrieval.

End-to-end data flow on the Soil Moisture Active Passive (SMAP) mission
2012 IEEE Aerospace Conference, 2012The Soil Moisture Active Passive (SMAP) satellite mission will provide measurements of the soil moisture and freeze/thaw state over the Earth's land surface, significantly enhancing knowledge of the Earth's water, energy, and carbon cycles. Collecting, transmitting, processing, and archiving the complete set of science and engineering data will be a ...

Frequency-Agile Radar Electronics for the Soil Moisture Active\/Passive (SMAP) Mission
IEEE Geoscience and Remote Sensing Magazine, 2015The radar aboard the Soil Moisture Active/Passive (SMAP) instrument is an L-band scatterometer/synthetic aperture radar (SAR) with uniquely designed capabilities for global retrieval of surface soil moisture. Several key science requirements have shaped the radar architecture, including requirements on terrestrial radio frequency interference (RFI ...

The zeroth-order radiative transfer model, also known as the tau-omega model, has been used extensively for decades in passive remote sensing of soil moisture. One approach, commonly known as the Dual Channel Algorithm (DCA), to retrieve soil moisture from this model is to make use of the H- and V-polarized brightness temperature (T B ) channels ...

The planned Soil Moisture Active Passive (SMAP) mission L-band radar/radiometer instrument
2011 IEEE International Geoscience and Remote Sensing Symposium, 2011The Soil Moisture Active/Passive (SMAP) mission is a NASA mission identified by the NRC “decadal survey” to measure both soil moisture and freeze/thaw state from space. The mission will use both active radar and passive radiometer instruments at L-Band.

Landscape freeze/thaw products from Soil Moisture Active/Passive (SMAP) radar and radiometer data
2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016The NASA Soil Moisture Active Passive (SMAP) mission produced a daily landscape freeze/thaw product (L3_FT_A) at 3-km spatial resolution derived from ascending and descending orbits of SMAP high-resolution L-band (1.4 GHz) radar measurements. Following the loss of the SMAP radar in July 2015, coarser (36-km) footprint passive microwave retrievals from ...

Agriculture is one of the most affected sectors by the flood. Spaceborn remote sensing is widely used for flood mapping and monitoring in recent decades. Some applications such as flood crop loss assessment require data with fine temporal resolution to monitor short-lived flood.

2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016
In this work, an integration of microwave data coming from different sensors (SMAP, Sentinel-1, AMSR2) has been attempted, in order to obtain an improved estimation of hydrological parameters and in particular of the Soil Moisture (SMC). The failure of radar sensor in SMAP satellite induced to look for other available microwave frequencies, both from ...

On the maneuvers operational response for NASA's soil moisture active-passive (SMAP) mission
2016 IEEE Aerospace Conference, 2016The Soil-Moisture Active-Passive (SMAP) spacecraft requires various kinds of in-orbit maneuvers over the course of its three-year mission. The types of maneuvers include preplanned commissioning maneuvers to reach its science orbit, regularly executed orbit maintenance maneuvers to overcome drag and other nominally occurring phenomena, as well as (the ...
