During the summer season of this year, several

cities of Peru were affected by the meteorological

event called “El Niño Costero”, originated by a

coastal warm sea surface temperatures that

produce storms and heavy rainfall.

The main city affected was Piura. It is located on

the North coast of Peru. The heavy rainfall and

floods caused numerous deaths and property

loss.

Remote sensing technology plays an important

role to study the clouds that caused the rainfall.

GOES 13 satellite pictures of NOAA were an

important assistant for the Meteorological and

Hydrological Weather Forecasters Service in

Peru.

The satellite pictures were used to successfully

analyzed the events that cause the rainfall in

Piura, the National Oceanic and Atmospheric

Administration's Weather and Climate Toolkit

(WCT) and Comprehensive Large Array-data

Stewardship System (CLASS) data were used to

visualize images of the GOES 13 geostationary

satellite and analyzed the episode of heavy rains

in Peru on March 25, 2017.

The area of work was the northern Peruvian

territory and data format requested was the

NetCDF. This NOAA WCT application could also

be used to analyze future GOES-R satellite data.

The satellite images were used to determine the

location of the cloud systems that were causing

heavy rains and subsequent flooding in the city of

Piura and many other cities on the northern coast

of Peru.

SET REFERENCE INFORMATIONWe found throught Rainfall Analysis Percentile, that

on March 25th occurred an extensive and extreme

rainfall along the city of Piura.

Another source such as Global Flood Monitoring

System (GFMS) of the University of Maryland, shows

that the intensity of rainfall was above 15 mm/h in

that region but this product can not be directly

downloaded and used in a GIS application..

SAVE INFORMATIONSave Image format

Save KMZ format

Infrared satellite picture,

shows the extensión of

convective clouds producing

heavy rainfall on Piura region

at 00 Z on 26th March.

The extension of clouds

covered more than 30,000

squares kilometer

The Weather and Climate Toolkit (WCT) has

been proven to be an good tool to analyze

GOES 13 Satellite pictures, during the rainy

season.

Although “El Niño Costero” event has affected

several places of Peru, this work only has

refered to Piura Region in Northern Peru.

Due this event, the evening of March 25th,

occurred one of most severe and vast rainfall

on the Piura Region.

WCT associated with NOAA CLASS data

helped to research about the convective

clouds that caused heavy rainfall in Perú.

This methodology could be used as a

reference to study past events, to analyze

GOES 13 satellite data and a near future GOES

R satellite pictures.

CLASS PROCESSINGCLASS is an electronic library of NOAA environmental data. The

CLASS web site (http://www.class.noaa.gov/) provides capabilities

for finding and obtaining GOES 13 satellite data among others.

WCT PROCESSING

The Weather and Climate Toolkit (WCT) of NOAA, provide an easyaccess to datasets of NOAA CLASS satellite archive data.WCT can be used as a tool to visualize GOES 13 satellite pictures, itcan export this pictures to other applications such as Google Earth,Arc GIS or QGIS to know the georeferenced places affected for therainfall.
