Quasi-SMAP: A SMAP-Referenced Long-Term Daily Surface Soil Moisture Record From 1981 to 2022
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingLong-term daily surface soil moisture records are important for hydrological, ecological, and drought-related applications. However, existing satellite soil moisture products still face a tradeoff among temporal length, daily spatial continuity, and ...

Evaluation of Satellite Soil Moisture Products Against Long-Term In-Situ Observations in Southern Iran [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information SciencesSoil moisture is vital for agricultural water management in semi-arid regions facing water scarcity. This study evaluated four satellite-based soil moisture products—SMAP Enhanced L3 Radiometer (9 km), SMAP 1 km downscaled (NSIDC), ASCAT SWI v3.0 (~

SMAPs: Short Message Authentication Protocols [PDF]
, 2017 There is a long history of authentication protocols designed for ease of human use, which rely on users copying a short string of digits. Historical examples include telex test keys and early nuclear firing codes; familiar modern examples include prepayment meter codes and the 3-digit card verification values used in online shopping.
