The Effect of Error Non-Orthogonality on Triple Collocation Analyses

Remote Sensing, 2022
Triple collocation analysis is an established technique for calculating the relative linear intercalibration coefficients and observation error variances for physical quantities measured simultaneously in space and time by three different observation ...

First attempt of global-scale assimilation of subdaily scale soil moisture estimates from CYGNSS and SMAP into a land surface model

Environmental Research Letters, 2021
Soil moisture performs a key function in the hydrologic process and understanding the global-scale water cycle. However, estimations of soil moisture taken from current sun-synchronous orbit satellites are limited in that they are neither spatially nor ...

Assessment of Level-3 Gridded Global Precipitation Mission (GPM) Products Over Oceans

Remote Sensing, 2019
The performance of Level-3 gridded Global Precipitation Mission (GPM)-based precipitation products (IMERG, Integrated Multi-satellite Retrievals for GPM) is assessed against two references over oceans: the OceanRAIN dataset, derived from oceanic ...

On the Trail of Creativity: Dimensionality of Divergent Thinking and Its Relation With Cognitive Abilities, Personality, and Insight

European Journal of Personality, EarlyView., 2020
Abstract Divergent thinking (DT) is an important constituent of creativity that captures aspects of fluency and originality. The literature lacks multivariate studies that report relationships between DT and its aspects with relevant covariates, such as cognitive abilities, personality traits (e.g. openness), and insight. In two multivariate studies (N

Evaluation of Sea Surface Wind Products from Scatterometer Onboard the Chinese HY-2D Satellite

Remote Sensing, 2023
The Chinese new marine dynamic environment satellite HY-2D was launched on 19 May 2021, carrying a Ku-band scatterometer (named HSCAT-D). In this study, wind products observed by the HSCAT-D were validated by comparing with wind data from the U.S ...

Multi-scale analysis of bias correction of soil moisture [PDF]

Hydrology and Earth System Sciences, 2015
Remote sensing, in situ networks and models are now providing unprecedented information for environmental monitoring. To conjunctively use multi-source data nominally representing an identical variable, one must resolve biases existing between these ...

Pseudospectral Calculation of the Wavefunction of Helium and the Negative Hydrogen Ion

, 2010
We study the numerical solution of the non-relativistic Schr\"{o}dinger equation for two-electron atoms in ground and excited S-states using pseudospectral (PS) methods of calculation.

Proposing a new integration system: Tolerance Merged Collocation comparative to Modified and Scaled Triple Collocation and weighting scheme to integrate four indices

Geomatics, Natural Hazards & Risk
The absence of a global standard for drought assessment has led to inconsistencies in observational methods. This study explores recent advancements in merging techniques to enhance drought monitoring, develop more reliable indices, and introduce a ...
