Dear GRADS Users<br>
<br>
This is not a GRADS question but I hope someone can help.<br>
<br>
I have a data set with precipitation flux (kg m-2 s-1). Does<br>
anyone know how can I convert to precipitation rate in (mm d-1)?<br>
<br>
Thanks<br>

Multiply by 3600.<br>
<br>
kg/m^2 is just a mass per unit area. If you divide by the density, you get<br>
meters. But since the density of liquid water at 0 C is 1000 kg/m^3, then<br>
kg/m^2/s is equivalent to mm/s.<br>

Hello,<br>
I just started ?using GrADS, can someone help me solve this problem?<br>
<br>
The reult I get is "Entire Grid Undefined"<br>
How can I solve this problem?<br>

Victor,<br>

This usually occurs, when you request (set) a grid(s) beyond the limits of<br>
the file. For example, you have a mean daily file with time ranging from 1<br>
to 150, and if "set t 151" you'll end up with this message "Entire Grid<br>
Undefined"! It's also true for z, y and x, which should be set based on<br>
your data information.<br>
<br>
So, when you open a file in Grads, before display it, first do this: "set q<br>
file". This will show you some useful information about the file that you<br>
have opened.<br>
