Definition
PRECIP consists of a set of 72 separate variables. These variables report the average precipitation in millimeters, received within a 10 kilometer circular buffer around each DHS cluster location, for the 60 individual months prior to the survey start date, the month of the survey start date, and the 11 individual months following the survey start date.
By adding PRECIP to your data cart, you are in effect adding 72 separate variables:
The 60 individual months prior to the survey start date, denoted by the number of months prior to the survey start date (e.g., PRECIP_01 is the average precipitation in the month before the survey start date; PRECIP_60 is the average precipitation in the 60th month before the survey start date).
The month of the survey start date (PRECIP_00)
The 11 individual months following the month of the survey start date, denoted by the number of months following the month of the survey start date (e.g., PRECIP_A01 is the average precipitation in the month following the month of the survey start date).
