2. Outline Introduction HRPT receive station HRPT system overview Line time data set Data and preprocessing Result Other applications Summary

3. High Resolution Sea Surface Temperature (SST) products in real time from AVHRR radiometer sensor on board NOAA polar satellites with 1 km spatial resolution received for the Instituto del Mar del Peru (IMARPE), since 1998. The information is used in diverse research field like monitoring events: El Niño (ENSO) La Niña, Upwelling and others. INTRODUCTION

4. RECEIVING STATION OF SATELLITE IMAGES HRPT (High Resolution Picture Transmission) CAPTURE REFERENCE REPORT & MAPS ANALYSISPROCESSING

5. HRPT station The HRPT station receive NOAA satellite data from 12, 14, 16, 17 y 18. The images have a raw format *.HRP - 1.1 km resolution at nadir - 3000 km by swath The received data since 1998 are recorded Cds. La estación HRPT include: -Antenna GPS (Trimble) -Dish antenna -Feed Horn/Downconverter -Demodulator -COMPAQ server 2. HRPT System Overview

22. Summary SST from AVHRR is a good tool for detecting oceans Structures like eddie, fronts, etc… The images are used to forecast events like NIÑO SST image is principaly used for fishers AVHRR images are usefull for coastal applications Future Improve the use of split windows algorithm Develop sst information for scientific community Open framework and Share information with GHRSST community
