Good Afternoon All,
I am trying to use a formula to convert some data in GrADS v2.2.1.
GrADS Formula (Broken down step-by-step for troubleshooting):
'define pratemmhr = (PRATEsfc.1*3600.0)' *converting mm/sec to mm/hour
'define step1 = pow(pratemmhr,1.6)'
'define step2 = (200.0*step1)'
'define step3 = log10(const(step2,0,-u))'
'define step4 = (10.0*step3)'
'define prate2dbz = step4'
I am receiving the following error in my Linux terminal:
Warning from LOG10: Data has 182085 values <= zero
These were set to the undefined value
What's going wrong here?
*Note, in Step 3, I have attempted to convert all undefined values to zeroes while log10() is called upon.
