A web API example requesting data for several hindcastDates (iterating over several hindcastYears, hindcastMonths and hindcastDays)
...
- Let's see how we can change the script above to iterate over several hindcastYears, hindcastMonths and hindcastDays efficiently
...
- Each hindcastDate is written into a separate file by setting the variable "target" accordingly.
...
- Please note that the objective of this python script is only to demonstrate how to make a MARS request efficient. You need to adapt it to your needs.
