What is the lowest amount of precipitation?

What is the highest precipitation ever recorded?

71.8 inches
Records show that the site of Foc-Foc received 71.8 inches of rain in a 24-hour period between January 7th and 8th, 1966, the highest ever recorded in the world.

How do you find missing rainfall data?

In this method simultaneous rainfall records of three close-by stations are made use of. The stations should however be evenly spaced around the station with missing records. A simple arithmetic average of the rainfall of the three selected stations gives the estimate of the missing value.

Is TRMM data free?

Precipitation data from the GPM and TRMM missions are made available free to the public in a variety of formats from several sources at NASA Goddard Space Flight Center.

How much precipitation does the US get per year?

On average, total annual precipitation has increased over land areas in the United States and worldwide (see Figures 1 and 2). Since 1901, global precipitation has increased at an average rate of 0.10 inches per decade, while precipitation in the contiguous 48 states has increased at a rate of 0.20 inches per decade.

What is the probability of precipitation in Canada?

Environment Canada. Environment Canada reports a chance of precipitation (COP) that is defined as “The chance that measurable precipitation (0.2 mm of rain or 0.2 cm of snow) will fall on any random point of the forecast region during the forecast period.”. The values are rounded to 10% increments, but are never rounded to 50%.

How are the annual values of precipitation calculated?

The annual values are averaged over 5-year periods, with the pentad label indicating the ending year of the period. Annual time series of the number of events are first calculated at individual stations. Next, the grid box time series are calculated as the average of all stations in the grid box.

What does pop stand for in weather forecasts?

A probability of precipitation (POP), (also expressed as: chance of precipitation, chance of rain) is a description of the likelihood of precipitation that is often published with weather forecasts.
