<span style="font-family: Aptos, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">We would like to share two community-serving model evaluation tools developed at NASA/NSF CCMC, ITMAP and CAMEL, and invite the community to explore them and provide feedback.</span></p>

<span style="font-family: Aptos, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">ITMAP (Ionosphere¨CThermosphere Model Assessment and Validation Platform) supports the evaluation of ionosphere and thermosphere models against observations. The platform covers
key parameters including ionospheric plasma density, GNSS Single Point Positioning (SPP), and thermospheric neutral density, and offers model comparisons, validation metrics, and visualizations.</span></p>
<p class="MsoNormal" style="text-align: left; text-indent: 0px; line-height: 18.4px; text-transform: none; margin: 0in 0in 8pt;">
<span style="font-family: Aptos, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">CAMEL (Comprehensive Assessment of Models and Events using Library tools) supports model evaluation across a broader range of space weather domains. Current capabilities include
parameters such as foF2 and hmF2, thermospheric neutral density and satellite drag, solar wind speed and density, parameters relevant to internal charging assessment, and ground magnetic perturbations. Users can compare model results with observations and
with other models using standard skill scores and interactive visualizations.</span></p>

better serve the model evaluation needs of the community. CCMC also invites model developers to contribute their model outputs and participate in the evaluations. </span></p>
