Monitoring Earth's Biosphere with the Orbiting Carbon Observatory

Discover how orbiting facilities precisely watch Earth’s biosphere breathe and grow, revealing profound economic and existential insights, while facing an immediate danger of complete decommissioning.

Short Summary

  • Understand how OCO satellites map atmospheric $\text{CO}_2$ using sophisticated spectral analysis.
  • Grasp the unexpected ability of OCO to measure plant photosynthesis (SIF) for drought and crop yield prediction.
  • Recognize the dual value of OCO for climate modeling, economic forecasting, and geopolitical monitoring.
  • Learn that the valuable OCO program faces imminent cancellation despite its low operating cost and high security return.

This episode details the technical function and profound dual utility (environmental and economic) of NASA's Orbiting Carbon Observatory (OCO) constellation. It stresses why losing this decade-long baseline of high-resolution Earth data represents a massive risk to global food security and intelligence gathering by 2025.

Description

Remove your personal information from the web at https://joindeleteme.com/SPACETIME One of the most important reasons we go to space is to know our own planet better. Today I'm going to tell you about an orbiting facility that literally watches Earth's biosphere breath and grow and die with incredible resolution. I'll talk about its profound existential and economic importance, and about why it's in danger of being lost. PBS Member Stations rely on viewers like you.

Thank you so much for talking about this. We can only hope that the OCOs aren't forced into early retirement.

In my personal budget, transportation that I use to get to work costs me money. Cutting that cost would mean I'm spending less, but then I can't get to work. When cutting a budget, don't cut the things that are profitable.

For some reason, this is the first PBS video showing up on my front page in 10 months, despite my regular viewing before.

Let's hope the OCOs get saved, as the running costs are peanuts compared to the broader budget (not counting the returns of this program)

We need to protect these programs like our lives depend on it. Because, well, they do.

The tragedy is that all these budgets cuts are being made to finance the tax giveaway to billionaires and monster corporations.
