How do you calculate missing precipitation data at a station?
The following methods are most commonly used for estimating the missing records.
- Simple Arithmetic Method.
- Normal Ratio Method.
- Modified normal ratio method.
- Inverse distance method.
- Linear programming method.
How do you find annual precipitation data?
Instructions. Precipitation data recorded in the NCDC dataset typically has the units: one-hundredth of an inch. Lets divide these values by 100 to get the precipitation time series in inches. Now, the total annual precipitation in your watershed is simply the sum of these precipitation values recorded in the year 2000 …
What is normal precipitation?
“Normal” precipitation does not equal “what you should expect.” “Normal” precipitation to a meteorologist is an average of the precipitation values over a 30-year period. Precipitation may very often be either well above or well below the seasonal average, or “normal.”
What do you mean by consistency of rainfall data?
If the curve comes out to be straight line then the rainfall data of the station under consideration is consistent. This is based on the principle that the mean accumulated precipitation of a number of stations which are meteorologically similar is not materially affected.
What is mass rainfall curve?
The mass curve of rainfall is a plot of the accumulated precipitation against time,plotted in chronological order. Records of float type and weighing-bucket typegauges are of this form. A typical mass curve of rainfall at a station during a storm is shown in fig 6.1.
Are there more precipitation stations than temperature stations?
There are many more precipitation stations than temperature stations, so the raw number of precipitation records will likely exceed the number of temperature records in most climatic situations. U.S. All Time Records Summary

How is a weather station defined in GHCN?
A station is defined as the complete daily weather records at a particular location, having a unique identifier in the GHCN-Daily dataset. For a station to be considered for any parameter, it must have a minimum of 30 years of data with more than 182 days complete each year.
