What is TRMM 3B42?

What is TRMM 3B42?

TRMM 3B42: 3-Hourly Precipitation Estimates. The Tropical Rainfall Measuring Mission (TRMM) is a joint mission between NASA and the Japan Aerospace Exploration Agency (JAXA) designed to monitor and study tropical rainfall.

What is Imerg data?

IMERG, the Integrated Multi-satellitE Retrievals for GPM, is a unified satellite precipitation product produced by NASA to estimate surface precipitation over most of the globe.

Where can I download precipitation data?

A precipitation data legend file can be downloaded at https://water.weather.gov/precip/archive/nws_precip_legend.avl.

How do I download data from Wunderground?

Re: Weather Underground Data Download In your WU account select Monthly View, select Table, highlight the text and Copy, past in new Excel sheet or text file of your choice. Works great!

What is climatological data?

A climatic data element is a measured parameter which helps to specify the climate of a specific location or region, such as precipitation, temperature, wind speed and humidity. Common data element durations available for the station could include monthly, daily, or hourly.

Can you export data from Weather Underground?

Export from WeatherUnderground using the CSV File Export Option to InfoSWMM. Step 2: The data imported from the csv file to Excel and after the text to columns tool is used looks like this in Excel. Step 3: You will need to format the new rounded time as a time format for import into a InfoSWMM time series.

What does NOAA stand for?

National Oceanic and Atmospheric Administration
National Oceanic and Atmospheric Administration U.S. Department of Commerce.

Who uses weather data?

This data is quality controlled then transmitted for use by a wide variety of users including utility companies, the media, climatologists, statisticians, and general weather enthusiasts.

Where does TRMM ( TMPA ) precipitation data come from?

This daily accumulated precipitation product is generated from the research-quality 3-hourly TRMM Multi-Satellite Precipitation Analysis TMPA (3B42). It is produced at the NASA GES DISC, as a value added product. Simple summation of valid retrievals in a grid cell is applied for the data day.

Which is better 3b43 or monthly TMPA?

In contrast, the relatively well-behaved 3B43 (monthly TMPA) forces the user to use data in calendar-month units; a monthly average from one month’s mid-point to the next is not possible.

What is the purpose of the 3b42 algorithm?

The purpose of the 3B42 algorithm is to produce TRMM- and raingauge-adjusted multi-satellite precipitation rate (in mm/hr) and root-mean-square (RMS) precipitation-error estimates.

How are IR and microwave data intercalibrated for TRMM?

All input microwave data are intercalibrated to TRMM Combined Instrument (TCI) precipitation estimates (TRMM product 2B31); the IR estimates are computed using monthly matched microwave-IR histogram matching; then missing data in individual 3-hourly merged-microwave fields are filled with the IR estimates.
