SASERAIN Interface Engine

(View the complete code for this example.)

This example shows how to retrieve past weather data for two locations (London and Paris) by using a date range. The historical (past) weather API is invoked because the DATE= and ENDDATE= options are specified. The concept of current conditions does not have any meaning when you specify past dates, so the historical weather data are returned instead of the current conditions. The output is shown in Output 53.6.1. When you specify past dates, the same data are returned whether or not you specify the CC= option. The SAS log shows the following warning:

*****WARNING: Using historical (past) weather API, so current conditions are 
not reported.
