Reanálisis BARRA-R2

Código GribStream: barrar2

Temperatura del aire de BARRA-R2 sobre Australia el 20 de enero de 2026 a las 04 UTC
Temperatura del aire a 1.5 m, válida el 20 de enero de 2026 a las 04:00 UTC. Esta vista australiana muestra las celdas nativas de BARRA-R2 sin suavizado; no representa la cobertura del dominio completo. La imagen usa °C; la API mantiene K. Fuente: Bureau of Meteorology, BARRA2, CC BY 4.0.

El tiempo australiano en su contexto histórico

El reanálisis regional determinista reconstruye el tiempo de Australia y sus alrededores a aproximadamente 12 km. BARRA-R2 pertenece a la familia BARRA2 del Bureau of Meteorology, que usa condiciones de borde de ERA5 para añadir detalle regional. El reanálisis combina observaciones y modelado físico; los valores de una celda son estimaciones, no mediciones de una estación.

Qué puedes consultar

La oferta inicial de GribStream incluye 28 campos horarios, de enero de 1992 a enero de 2026: temperatura cerca de superficie y superficial, humedad, viento en superficie y a altura de turbina, ráfagas, presión, precipitación, radiación solar y de onda larga, nubosidad, evaporación, CAPE y CIN. Los valores ausentes en la fuente permanecen ausentes.

Son condiciones históricas horarias con plazo de pronóstico cero. BARRA2 no es un pronóstico en tiempo real; los nuevos datos históricos pueden publicarse con retrasos importantes. Los campos instantáneos usan horas en punto; los promedios y extremos de una hora usan el punto medio del intervalo, a la media hora. El inventario los distingue con 1h_mean, 1h_minimum y 1h_maximum. La precipitación es una tasa y la radiación solar directa corresponde a una superficie horizontal, no a irradiancia directa normal. Otros campos, frecuencias y BARRA-RE2 quedan fuera de esta oferta inicial.

Planeamos incorporar pronto todos los parámetros C2/R2 y el registro completo disponible desde 1979. Contáctanos para más información o una necesidad concreta de cobertura.

Preguntas que este registro ayuda a responder

Compara períodos cálidos y fríos, relaciona el tiempo con la demanda energética, investiga recursos eólicos y solares o sitúa lluvias en su contexto histórico. Contrasta la reconstrucción con observaciones en los lugares relevantes. Una grilla más fina por sí sola no garantiza más precisión.

Límites científicos y atribución

Consulta los problemas conocidos del proveedor, incluidos los efectos cerca de los bordes del dominio. Los sesgos del modelo y de las observaciones importan al interpretar extremos locales. Atribuye al Australian Bureau of Meteorology bajo CC BY 4.0 y conserva el producto y la versión usados.
