Monitoramento da Seca em Pernambuco via ERA5-Land (1950-2025): Dados de Reanálise, Scripts de Validação e Visualizações Hidro-Termodinâmicas.

Description

[PT] Este dataset e framework analítico fundamentam o estudo da seca em Pernambuco (1950-2025) utilizando reanálise ERA5-Land. O trabalho valida o modelo contra dados do INMET ($R^2=0,944$ para precipitação) e aplica indicadores termodinâmicos (Razão de Bowen, ESI e umidade do solo em profundidade) para diagnosticar o desacoplamento hídrico e a intensificação da aridez no Semiárido brasileiro.

[EN] This dataset and analytical framework support the drought study in Pernambuco, Brazil (1950-2025), using ERA5-Land reanalysis. The work validates the model against INMET data ($R^2=0.944$ for precipitation) and applies thermodynamic indicators (Bowen Ratio, ESI, and deep soil moisture) to diagnose water decoupling and the intensification of aridity in the Brazilian Semiarid region.

[ZH] 该数据集和分析框架支持使用 ERA5-Land 再分析对巴西伯南布哥州干旱(1950-2025 年)进行的研究。该工作针对 INMET 数据验证了模型(降水量 $R^2=0.944$),并应用热力学指标(波文比、ESI 和深层土壤水分)来诊断巴西半干旱地区的水分失耦和干旱加剧现象。

El trabajo valida el modelo frente a datos del INMET ($R^2=0,944$ para precipitación) y aplica indicadores termodinámicos (Razón de Bowen, ESI y humedad del suelo en profundidad) para diagnosticar el desacoplamiento hídrico y la intensificación de la aridez en el Semiárido brasileño.

[FR] Cet ensemble de données et ce cadre analytique soutiennent l'étude de la sécheresse dans le Pernambouc, Brésil (1950-2025), en utilisant la réanalyse ERA5-Land. Le travail valide le modèle par rapport aux données de l'INMET ($R^2=0,944$ pour les précipitations) et applique des indicateurs thermodynamiques (rapport de Bowen, ESI et humidité profonde du sol) pour diagnosticar le découplage hydrique et l'intensification de l'aridité dans la région semi-aride brésilienne.

[DE] Dieser Datensatz und der analytische Rahmen unterstützen die Dürrestudie in Pernambuco, Brasilien (1950-2025), unter Verwendung der ERA5-Land-Reanalyse. Die Arbeit validiert das Modell gegen INMET-Daten ($R^2=0,944$ für Niederschlag) und wendet thermodynamische Indikatoren (Bowen-Verhältnis, ESI und tiefe Bodenfeuchtigkeit) an, um die Wasserentkopplung und die Intensivierung der Aridität in der semiariden Region Brasiliens zu diagnostizieren.
