Combining FY-3D MWTS-2 with AMSU-A Data for Inter-Decadal Diurnal Correction and Climate Trends of Atmospheric Temperature

open access: yesRemote Sensing, 2021
Microwave temperature sounding observations from polar-orbiting meteorological satellites have been widely used for research on climate trends of atmospheric temperature at different heights around the world.

An Efficient Continuous Data Assimilation Algorithm for the Sabra Shell Model of Turbulence [PDF]

open access: yes, 2021
Complex nonlinear turbulent dynamical systems are ubiquitous in many areas. Recovering unobserved state variables is an important topic for the data assimilation of turbulent systems. In this article, an efficient continuous in time data assimilation scheme is developed, which exploits closed analytic formulae for updating the unobserved state ...

Data Assimilation Networks

open access: yesJournal of Advances in Modeling Earth Systems, 2022
AbstractData Assimilation aims at estimating the posterior conditional probability density functions based on error statistics of the noisy observations and the dynamical system. State of the art methods are sub‐optimal due to the common use of Gaussian error statistics and the linearization of the non‐linear dynamics.

A High Resolution Reanalysis for the Mediterranean Sea

open access: yesFrontiers in Earth Science, 2021
In order to be able to forecast the weather and estimate future climate changes in the ocean, it is crucial to understand the past and the mechanisms responsible for the ocean variability.

Data assimilation in glaciology [PDF]

open access: yes, 2014
Abstract This chapter addresses an inverse problem in glaciology, namely how to infer a climatic scenario (i.e. how to reconstruct past polar temperature) from ice volume records. Ice volume observations are available from oceanic records, giving information about sea level, and therefore about the amount of water stored in ice sheets ...

Determining Tropical Cyclone Center and Rainband Size in Geostationary Satellite Imagery

open access: yesRemote Sensing, 2022
Brightness temperature (TB) observations at an infrared channel (10.3 μm) of the Advanced Baseline Imager (ABI) on board the U. S. 16th Geostationary Operational Environmental Satellite (GOES-16) are used for determining tropical cyclone (TC) center ...

Mitigation of Significant Data Noise in F17 SSMIS Observations since October 2017

open access: yesRemote Sensing, 2022
Special Sensor Microwave Imager Sounder (SSMIS) temperature sounding observations have been made available since the launch of the Defense Meteorological Satellite Program (DMSP), F16, on 18 October 2003. These conical-scanning observations of brightness

Data Assimilation for Chaotic Dynamics [PDF]

open access: yes, 2022
Chaos is ubiquitous in physical systems. The associated sensitivity to initial conditions is a significant obstacle in forecasting the weather and other geophysical fluid flows. Data assimilation is the process whereby the uncertainty in initial conditions is reduced by the astute combination of model predictions and real-time data.

Effects of stocking density on the performance of lettuce (Lactuca sativa) in small‐scale lettuce‐Nile tilapia (Oreochromis niloticus L.) aquaponic system

open access: yesAquaculture, Fish and Fisheries, Volume 2, Issue 6, Page 458-469, December 2022., 2022
Graphical Abstract : Aquaponics, hydroponics, stocking density. Abstract Aquaponics incorporates aquaculture with hydroponics, whose principles and operations largely remain untested. Currently, there is a knowledge gap on the performance of aquaponic systems used for fish production under different stocking densities.

Tracking the Early Movements of Northeast China Cold Vortices Using FY-3D MWTS-2 Observations of Brightness Temperature

open access: yesRemote Sensing, 2022
The Northeast China cold vortex (NCCV) often occurs in spring and summer, causing extreme weather such as rainstorm and hail in Northeast China. The brightness temperature (TB) observations of Microwave Temperature Sounder-2 (MWTS-2) on board Fengyun-3D (
