Understanding the Global Variability in Thermospheric Nitric Oxide Flux Using Empirical Orthogonal Functions (EOFs) [PDF]

open access: yesJournal of Geophysical Research: Space Physics, 2018
Abstract We present the first‐ever global assessment of thermospheric nitric oxide infrared radiative flux (NOF) variability. NOF (W/m 2 ) from 100‐ to 250‐km altitude is extracted from 13.7 years of data from the TIMED satellite, Sounding of the Atmosphere using Broadband ...

An Alternative to PCA for Estimating Dominant Patterns of Climate Variability and Extremes, with Application to U.S. and China Seasonal Rainfall

open access: yesAtmosphere, 2020
Floods and droughts are driven, in part, by spatial patterns of extreme rainfall. Heat waves are driven by spatial patterns of extreme temperature. It is therefore of interest to design statistical methodologies that allow the rapid identification of ...

A multivariate climate index for the western coast of Colombia [PDF]

open access: yesAdvances in Geosciences, 2013
Indices of the interannual and interdecadal variability at Tumaco Island (2° N; 79° W; Colombia), based on time series of sea surface temperature (SST), air temperature (AT) and precipitation (P) from a coastal station, are presented regarding the period

Analysis of rainfall patterns in Kalimantan using fast fourier transform (FFT) and empirical orthogonal function (EOF)

open access: yesJournal of Physics: Conference Series, 2021
Abstract Rainfall patterns in Kalimantan are generally divided into 2 types, namely monsoonal and equatorial. The pattern can be determined by analyzing the 6-month frequency of rainfall signal. This analysis has been carried out on general data in Indonesia, but no one has yet examined it in detail in Kalimantan.

Research on Short-term Ionospheric Prediction Combining with EOF and ARIMA Model Over Guangxi Area [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020
According to the empirical orthogonal function (EOF), the non-stationary time series data are decomposed into time function and space function, so this mathematical method can simplify the non-stationary time series and eliminate redundant information ...

The Influence of Beachrock Outcrop on Spatial Variability in Beach Morphology

open access: yesJournal of Marine Science and Engineering
Beachrock is a type of coastal carbonate sedimentary rock developed in the sandy beach intertidal zone, widely distributed along the beach front, and the loss of beach sediment is the main cause of beachrock exposure.
