1 satellite techniques for measuring surface temperatures: INGV participation to ESA DUE GLOB Temperature Maria Fabrzia Buongiorno, Massimo Musacchio, Malvina Silvestri,, Claudia Spinetti, Laura Colini, Stefania Amici, Valerio Lombardo Variables (GMECV)

2 The INGV Remote Sensing Group has a large and consolidated experience in processing Satellite and airborne multispectral and hyperspectral data to observe natural phenomena CONTRIBUTION TO ESA PROJECTS ESA-GLOBTEMP (as USER) ESA-GEP ( Responsible for development a processing chain for surface temperature), participation to the Volcano Trial Case (VO-2 trial case of the ESA DRR GSP) ESA-VEGAN (impact of volcanic eruption on vegetation), active role of End Users in Argentina and Italy Past activities in ESA and ASI projects for geophysical activities and contributes to the study of ESA IR element, Sentinel Convoy SPECIFIC EXPERTISE: Development of procedures to analyse surface Temperatures, pecific gas species emitted from natural sources, fire thermal characteristics Study of long time series of EO data and ground measurements Data ASTER, LANDSAT, HYPERION, AVHRR, MODIS from 2016 SENTINEL3 and SENTINEL2 Field measurements for CAL/VAL of EO data and products Availability of permanent and systematic measurements as Mt. Etna and Campi Flegrei in Italy. Study of new IR missions to support Climate Change studies. Participation to national and international Science Teams for Optical Missions.

3 Within CCI Objectives and Scope Land temperaure Contribute to the Development of new ECVs Cross-ECV scientific exploitation (demonstration) Analysis of temperature variation using high spatial resolution TIR data, mountain areas Time series analysis Snow cover & Land cover Fire disturbance Specific gas emissions Cross-ECV scientific exploitation (demonstration) Contribute of snow cover changes on volcanoes Time series analysis New R&D on ECVs that were started in CCI HYPERSPECTRAL DATA USE consolidation of algorithms to study the fire fronts development and consolidation of algorithms for measure CO2 emitted from sources on land

4 INGV CONTRIBUTE TO GMECV PROPOSED VARIABLES LAND SURFAC TEMPERAURE TEMPERATURE- EMISSIVITY ALGORITHMS UNDERSTAND CHANGES AT LOCAL SCALE APPLICATION WORLDWIDE LANDSAT,ASTER, SENTINEL2 SENTINEL3 CALIBRATION/ VALIDATION USING ON ITALIAN VOLCANOES AVAILABILITY OF PERMANENENT GROUND INSTRUMENTS SNOW COVER AND LAND COVER TEMPORAL ANALYIS OF SNOW COVER VARIATION PROVIDE MAPS FOR END USERS AS PARCO DELL ETNA LAND COVER VALIDATION FOR CEOS LANDSAT SENTINEL2 FIRE DISTURBANCE AND GAS EMISSIONS DEVELOPMENT OF SPECIFIC ALGORITHMS FOR ACTIVE FIRES, FIRE SCARS GAS EMISSIONS FROM NATURAL SOURCES USE OF AIRBORNE and SPCEBORNE HYPERSPECTRAL SENSORS HYPERION,PRISMA SRNTINEL3-OLCI

5 Variance 1 The primary interest is to contribute to the study of LAND SURFACE TEMPERATURE Variation also considering the necessity to increase the knowledge on LAND EMISSIVITY and Atmospheric contributes. 3 2,5 AVHRR and ASTER TIR data cross-comparison for 2006 eruption AVHRR TIR variance ASTER TIR variance 2 1,5 1 0,5 0 28/05/ /06/ /07/ /07/ /08/ /09/ /09/ /10/ /11/ /11/2006 Date (dd/mm/yyyy) 2 analyze large time series of surface temperature images orginated from LANDSAT, ASTER to integrate and cross-validate, global maps obtained by AATSR, MODIS followed by SENTINEL3 and SENTINEL2 (to map high temperature events). Continuity with GLOBTEMP project

6 INGV PROPOSED ACTIVITIES AND CONTRIBUTES FOR ESA CCI and ASI Initiatives Participation to international community involved i study Land Surface Temperature (LST), land cover ground gas emissions. Contribute to development of procedures and provide products based on EO data. Interest in contributing to next ESA Activities regarding LST Offer the INGV permanent and systematic ground measurements on volcanic areas to Calibrate and validate LST products Active International collaborations: USGS, NASA-JPL, Volcano Observatories, National Parks Contribute to the understanding of the climate change effects on the Italian territory With specific application to study the complex interaction between natural and human induced phenomena on environment: test areas Parco dell Etna which is UNESCO site, extend to Eolian Archipelago (also UNESCO) Support ASI and ESA on the study of new space missions New instruments to complement the existing instruments to better understanding the Changing Earth (EXPLORERS, NEW SENTINELS, HYPERSPECTRAL MISSIONS). In particular MIR-TIR imaging spectrometer with a ground resolution in the range of SENTINEL2/LANDSAT8 (30-60 m), which will add very important information to understand the Climate Change effects at local scale and integrate information at different scales
