Climate Data and Social Vulnerability Integration

Exploring the intersection of climate extremes and vulnerable populations

Developed by ISciences, LLC with funding from the ESIP Lab grant program

ISciences Logo ESIP Logo

Project Overview

Climate change is increasing the frequency and severity of extreme weather events, making it vital to understand current climatic conditions, compare them to historical baselines, and identify vulnerable populations. The nClimGrid Explorer addresses this challenge by providing tools to access, analyze, and visualize NOAA's nClimGrid-Daily dataset and integrate it with NASA's U.S. Social Vulnerability Index (SVI) Grid data.

This application was developed by ISciences, LLC with funding support provided through the Earth Science Information Partners (ESIP) Lab grant program. Following open science principles, this application makes advanced climate-vulnerability analysis accessible to a broader audience through an intuitive web interface.
