1. The Clarus Initiative
2. The Clarus Initiative Clarus is an R&D initiative to demonstrate the value of “Anytime, Anywhere Road Weather Information”
The objective is to enable public agencies and the private weather enterprise to meet the information needs of all transportation users and operators
To do so, we needed to create a robust
data assimilation,
quality checking, and
data dissemination
system that provides near real-time atmospheric and pavement observations from the collective states’ investments in environmental sensor stations (ESS).
3. Clarus Development Milestones
4. ESS Deployments by State DOTs
5. Clarus System Data Flows Nationwide participation of all public transportation agencies in Clarus
Consensus on dissemination and disclaimers
Sustainable system functionality through transition to NOAA
Implement a new generation of QCh algorithms
Provide meaningful ESS network health summary for DOT administrators

Anytime, Anywhere Road Weather Information
7. Regional Demonstration Phases Phase 1: Request for Applications (RFA)
State-based approach
Creation of ConOps tailored to agencies’ needs
Phase 2: Connection Incentive Program (CIP)
Build public agency participation in Clarus
Offset some costs for metadata & data access
Phase 3: Request for Proposals (RFP)
Private sector to build & test the ConOps
Independent evaluation of the Clarus System
8. Phase 3 Use Case Scenarios 5 use case scenarios
Based upon ideas within Phase 1 ConOps
Scenarios focus on improving
Surface transportation meteorology,
Decision support tools, &
Control & advisory strategies
