Descripción

CFS Isentropic entrega campos del Climate Forecast System sobre superficies de temperatura potencial constante. Estas superficies ayudan a seguir transporte de masas de aire y dinámica de altura con una lectura distinta a los niveles de presión tradicionales.

El dataset cfsipvf incluye campos como vorticidad potencial, función de corriente y gradiente térmico vertical (lapse rate), que sirven para estudiar corrientes en chorro, vaguadas, frentes, estabilidad y acoplamientos entre troposfera y baja estratosfera.

En GribStream, CFS Isentropic es útil cuando necesitas contexto dinámico de horizonte extendido sin descargar archivos GRIB completos: planificación de aviación, diagnósticos de altura, estudios atmosféricos o comparación contra CFS Pressure.

Permite consultar puntos, grillas, /timeseries y /runs con el mismo patrón de API que los demás modelos en GribStream, manteniendo exactos los códigos y selectores de la fuente.
