Satellite soil moisture observations often require the enhancement of spatial resolution prior to being used in climatic and hydrological studies. This study employs the thermal inertia theory to downscale the 36 km radiometric data of the NASA’s Soil Moisture Active/Passive Mission (SMAP) into 1 km resolution. Regressions between daily temperature difference and daily mean soil moisture were e...

BACKGROUND Complications of peritoneal dialysis (PD) such as pain and catheter leakage are frequently reported. Delayed bowel perforation of a PD catheter is a rare adverse event but a serious complication associated with significant mortality. Bowel perforation of a PD catheter is difficult to differentiate from PD-related peritonitis and likely to result in a delay in diagnosis. Here, we repo...

To meet the demand of regional hydrological and agricultural applications, a new method named near infrared-red (NIR-red) spectra-based disaggregation (NRSD) was proposed to perform a disaggregation of Soil Moisture Active Passive (SMAP) products from 36 km to 250 m resolution. The NRSD combined proposed normalized soil moisture index (NSMI) with SMAP data to obtain 250 m resolution soil moistu...

We propose a language modeling and adaptation framework using Bayesian structural maximum a posteriori (SMAP) principle, in which each n-gram event is embedded in a branch of a tree structure. The nodes in the first layer of this tree structure represent the unigrams, and those in the second layer represent the bigrams, and so on. Each node in the tree structure has an associated hyper-paramete...

Two experiments were conducted to examine the role of three facets of numeracy (objective (ONS), subjective (SNS), and symbolic number mapping (SMap)) in three anchoring tasks (experimenter-given, self-generate, and valuation). We found that the three numeric competencies were associated with different anchoring tasks. SMap was associated with none of the three anchor tasks, while ONS consisten...

Achieving the soil moisture retrieval goals set for the SMAP mission [1]-[2] requires avoiding any significant degradations of SMAP’s L-band radiometer observations. Radio Frequency Interference (RFI) is an important risk factor, even given the “protected” status of the 1400-1427 MHz band within which the radiometer operates. RFI forecasts based on known radar sources were used in initial plann...

As spacecraft send back increasing amounts of telemetry data, improved anomaly detection systems are needed to lessen the monitoring burden placed on operations engineers and reduce operational risk. Current spacecraft monitoring systems only target a subset of anomaly types and often require costly expert knowledge to develop and maintain due to challenges involving scale and complexity. We de...

Spatial and temporal variation in soil moisture plays a significant role in establishing efficient irrigation scheduling, climate change prediction, and sustainable land and water management. Passive microwave remote sensing at L-band is widely recognised as the preferred technique to measure surface soil moisture globally, with spatial resolution ranging from 40-100km. However, passive microwa...

A multi-spectral SPOT image, polarimetric airborne SAR data as well as satellite based C-band SAR data have been used to perform classification of agricultural fields and areas occupied by forest and lake. Conventional Maximum Likelihood classification has been compared with classification incorporating a Gaussian mixture class model, as well as an algorithm based on multi-resolution structured...
