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.  
 
 
Type 0 - primary identification record; this record occurs whenever  
         there is a change in any one of the following parameters -  
         source of data, source of identification, WMO#, latitude, 
         longitude, elevation, 721#, 995#. See Table 1  
 
character  1     type 0 
character  2-7   WMO # 
character  8-11  year  
character 14     month (1-12) 
character 15     source of data 
character 16     ship indicator 
character 17-20  latitude

character 26-29  elevation 
character 30-35  721# 
character 36-44  995# 
character 45-50  blanks  
 
Type 1 - secondary identification record; always occurs after type 0 
 
charcater  1     type 1  
character  2-13  same as type 0

character 44-50  blanks  
 
Type 2-5 - record of height parameters (Table 3). When they exist, these  
           records will occur only once for each year. Types 3-5 occur only  
           when there are additinal heights assosciated with SFc pressure, 
           temperature, and precipitation.

character 26-31  height above MSL to which station pressure is reduced 
character 32-37  height of thermometer above ground  
character 38-43  height of thermometer above MSL 
character 44-49  height of rim of precipitation gauge above ground  
character 50     blank 
 
Type 6 - record of standard parameters for the month given (Table 2) 
 
character  1     type 6
