The Impact of Spatial Dynamic Error on the Assimilation of Soil Moisture Retrieval Products

Remote Sensing
Soil moisture is a key factor affecting the exchange of heat and water between the land and the atmosphere. Land data assimilation (LDA) methods that leverage the strengths of both models and observations can generate more accurate initial conditions ...

Observing Patterns of River Usage

Safety, 2019
Rivers are a leading location for drowning, yet little is known about people’s usage of these waterways. This pilot study aimed to test the use of direct observations to calculate river usage. Direct observations were conducted at regular intervals

Vicarious neural processing of outcomes during observational learning. [PDF]

PLoS ONE, 2013
Learning what behaviour is appropriate in a specific context by observing the actions of others and their outcomes is a key constituent of human cognition, because it saves time and energy and reduces exposure to potentially dangerous situations ...

Phase-Dependent Properties of Extrasolar Planet Atmospheres

, 2005
Recently the Spitzer Space Telescope observed the transiting extrasolar planets, TrES-1 and HD209458b. These observations have provided the first estimates of the day side thermal flux from two extrasolar planets orbiting Sun-like stars.

On the location uncertainty of early-instrumental earthquakes

Seismica
Uncertainty in reported body-wave arrival times is a key contributor to earthquakes location error estimates, especially in the early-instrumental period (e.g., prior to the early 1960s).

Testing the Distance-Duality Relation with a Combination of Cosmological Distance Observations

, 2011
In this paper, we propose an accurate test of the distance-duality (DD) relation, $\eta=D_{L}(z)(1+z)^{-2}/D_{A}(z)=1$ (where $D_{L}$ and $D_{A}$ are the luminosity distances and angular diameter distances, respectively), with a combination of ...

Quantifying UAS Observation Error Variance Used in Data Assimilation Systems and Its Impact on Predictive Skill

Journal of Advances in Modeling Earth Systems
Observation error determines the weights of the observations and background state used in data assimilation to generate analyses. Quantifying observation error is critical for the optimal assimilation of observational data sets. Uncrewed Aircraft System (
