DATOS MENSUALES - NCAR
Se dispone de un listado de estaciones que contiene:
1) Numero de la W.M.O. de la estació:n.
2) Nombre de la estación.
3) Fecha - mes (MM) y año -.
4) Latitud y longitud (LAT y LON) en grados y minutos.
5) Altura de la estacion (MULTIPLICAR POR 10 Y RESTAR POR MIL) (en metros).
Cada registro indica las estaciones presentes y los cambios
- si los hubiera - en su posición geográfica.
Se indica como " END OF DATA AT:" el ultimo mes y año en el cual
hay datos.
A continuación se transcribe el formato (en inglés), de donde se puede determinar las variables y
estadísticos disponibles.
