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 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.
