Milani Teaches Earth Science Abroad

This month, the 2023 Global Precipitation Measurement Mission (GPM) Mentorship program comes to an end. The project, coordinated by ESSIC Assistant Research Scientist Lisa Milani with the help of colleagues Andrea Portier and Vaso Mantas, involved ten Italian teachers from four different schools. The effort included three lectures about “the Water Cycle”, “Weather and Climate” and “GPM products and applications” and targeted middle- and high-school teachers aiming to apply outreach material in the classroom context. After the three lectures, the teachers involved their students in a practical project applying language, programming and science contents and skills.

Figure 5. (a, b) The analysis RMSE under full-coverage observing network for the atmosphere (a) and ocean (b) with the SC 3D-VAR (green), 4D-Var (blue), 4D-Var/3DFGAT CERA (cyan dash), 40-member ETKF (red), and 20-member ETKF (gray) for the last 1000 d. Time-averaged analysis RMSE for the last 13.7 years for all methods are shown in the figure. Panels (c) and (d) are similar to (a) and (b) except for only assimilating atmosphere observations. Adapted from Penny et al. (2019) and Da (2022).

Towards Strongly Coupled Ensemble Data Assimilation

A team of international researchers led by ESSIC Scientist Distinguished University Professor Eugenia Kalnay and including Dr. Cheng Da recently reviewed their latest research progress on coupled data assimilation in a new paper published in Nonlinear Processes in Geophysics titled, “Review article: Towards strongly coupled ensemble data assimilation with additional improvements from machine learning”.

Relationship Between the Aerosol Loadings Over the Bay of Bengal and the Arabian Sea in the Early Summer and Asian Monsoon Rainfall Anomalies, and the Role of SST Anomalies in the Indian Ocean

ESSIC/CISESS Scientist Yongsheng Zhang recently published a study on the year-by-year
aerosol variations over the Bay of Bengal (BoB) and Arabian Sea (AS) in early spring and their
relationship to the Asian summer monsoon rainfall anomalies using satellite-observed aerosol
products.
