Remote Sensing, 2019 The spatio-temporal characteristic of rainfall in the Beles Basin of Ethiopia is poorly understood, mainly due to lack of data. With recent advances in remote sensing, satellite derived rainfall products have become alternative sources of rainfall data ...

ENSO or the Atlantic: Which Actually Governs the Hydrological Vulnerability of the Caatinga?
International Journal of Climatology, EarlyView.This study challenges the traditional ENSO‐centric paradigm of rainfall variability in the Caatinga by demonstrating that the Tropical Atlantic exerts a statistically dominant influence on regional hydrological vulnerability. Using a seasonal ARX/HAC model and CHIRPS data, we establish a new hierarchy of climatic drivers across six rainfall districts ...

Chirped Attosecond Photoelectron Spectroscopy
Physical Review Letters, 2006 We study analytically the photoionization of a coherent superposition of electronic states and show that chirped pulses can measure attosecond time scale electron dynamics just as effectively as transform-limited attosecond pulses of the same bandwidth.

Nonlinear frequency modulation chirps for active sonar
, 1999 Range sidelobe suppression in pulse-compression radars and sonars is conventionally performed using amplitude windowing in either the time or frequency domains.

International Journal of Climatology, EarlyView.The Congo Air Boundary (CAB) occurs where two air masses with different humidities meet over Africa. The CAB is investigated in three reanalyses, datasets combining observations with forecasts. Between 1980 and 2010, the reanalyses show that when the CAB reduces in daily frequency between August and December, rainfall over central southern Africa ...

Individual acoustic variation in Belding’s ground squirrel alarm chirps [PDF]
, 2002 The acoustic structure of calls within call types can vary as function of individual identity, sex, and social group membership and is important in kin and social group recognition.

International Journal of Climatology, EarlyView.Southwest Asia remains understudied in high‐resolution regional climate modelling despite its climatic sensitivity and complex orography. We compare WRF (10 km), CESM (~2°), and ERA5 (0.25°) for 1950–2002, with supplementary validation against CHIRPS and PERSIANN‐CDR. WRF corrects the unrealistic summer precipitation overestimation of CESM and improves

Land Degradation &Development, EarlyView.ABSTRACT Soil erosion remains a major environmental challenge in Nigeria, driven by the combined effects of climate variability and land use/land cover (LULC) changes. Understanding future dynamics is essential for effective soil conservation planning.
