  1. AeroStat: NASA Giovanni Tool for Statistical Intercomparison of Aerosols AGU FM11 ID: IN51C-1604 Jennifer.C.Wei@nasa.gov Jennifer C.Wei1, Gregory Leptoukh2, Chris Lynnes2, Arif Albayrak1, Maksym Petrenko3, Mahabaleshwara Hegde1, Leonid Petrov1, Daniel da Silva2, and Charles Ichoku2(1Adnet, 2NASA GSFC, 3UMCP) Giovanni Social Network Giovanni AeroStat Bias Adjustment Satellite Data Data Quality Motivation: Goals: • Different papers suggested different views on the quality of MODIS and MISR aerosol products. • Peer-reviewed papers are usually behind the latest version of the data. • Difficult to verify/reproduce results from various published paper • Difficult to combine consistently adjusted measurements • In need of an online shareable environment where data processing and analysis can be done in a transparent way by any user of this environment and can be shared amongst all the members of the aerosol community. • Provide an easy-to-use collaborative environment for exploring aerosol phenomena using multi-sensor data • Provide consistent services with multi-sensor aerosol data • Provide a transparent environment to colocation and comparison methods with detail documentation • Provide easy sharing of results Data Merge Ground-Based Data Lineage Process Filters Data Statistical Analysis Real-Time Collaboration • Original Level 2 Product: • AERONET, MODIS Terra, MODIS Aqua, MISR • Derived Products • Satellite Colocated with AERONET stations: MAPSS Database • Cross Satellite Colocations: Near Neighbor Search AeroStat Data Are Derived from Level 2 Measurements Flowchart of Bias Adjustment using Neural Network (Details in Poster A53C-0371) Time Series Bias Adjustment No QA QA Aerostat Giovanni Online Services Bias Adjustment No QA QA Scatter Plot Lat-Lon Map Dark Target Land Deep Blue Merged (Deep Blue + Dark Target) User Selects a bounding box How does Giovanni-Social work? (Details in Oral IN33E-05 at 2:40 – 2:55 pm Wednesday) Step1: Create an account on http://gsocial.ecs.nasa.gov Data Merge: Satellite Data Only (Max. 10 Days Period) Step2: Share/Save your Giovanni results from http://giovanni.gsfc.nasa.gov/aerostat/ Data Quality Filters Threshold Max. bounding box is 50 degrees Default: Science Team Recommendation Post concerns/questions Example of Giovanni-Social work via sharing: Responding comments Add Annotation Allow up to 8 variables (including QA options) Case Study: Dust Storm Episode (March 1 ~ 5, 2003) Down the Road: Dust Storm Transport (Multi-sensors products merged) Extremely High AOD • Add/Integrate bias adjustment for MISR colocated with AERONET data • Add/Integrate bias adjustment for “Satellite Only” service • Routinely process and ingest of colocated satellite and AERONET data • Fold AeroStat Giovanni into main stream Giovanni • Add new Giovanni features and services to AeroStat where applicable http://giovanni.gsfc.nasa.gov/aerostat/ This project was supported in by ACCESS (Accelerating Collaborative Connections for Earth System Science)
