Highlights from last month:

K Nearest Neighbors

Fred Rogers

K Nearest Neighbors (KNN) is a supervised machine learning method that "memorizes" (stores) an entire dataset, then relies on the concepts of proximity and similarity to make predictions about new data. The basic idea is that if a new data point is in some sense "close" to existing data points, its value is likely to be similar to the values of its neighbors. In the Earth Systems Sciences, such techniques can be useful for small- to moderate-scale classification and regression problems.

Exploring Indigenous Data Sovereignty

The concept of Indigenous Data Sovereignty (IDS) asserts that data generated by Indigenous peoples, including data generated from their land and resources, should be governed by the people themselves. Environmental observations collected on native lands are one small part of the IDS context, and they were the subject of a recent workshop hosted by the Southwestern Indian Polytechnic Institute (SIPI) in Albuquerque, New Mexico.

Registration is open for the 2024 Pythia Cook-off! This U.S. National Science Foundation-funded hackathon for Cookbook development will grow participants’ Python coding, communication, collaboration, and educational development skills, while expanding the collection of Pythia Cookbooks for the open source, open science community. Pythia Cookbooks are crowd-sourced collections of domain-specific tutorials and exemplar workflows, building on existing Pythia Foundations tutorials. Cookbooks are supported by a rich GitHub-based infrastructure enabling collaborative authoring and automated health-checking to ensure reproducibility.

NSF Unidata Committee Nominations Open

NSF Unidata committee members

NSF Unidata is governed by its community. Our Strategic Advisory and Users committees facilitate consensus-building for future directions of the NSF Unidata Program and establish standards of involvement for the community. Direct involvement in the Program by the academic community helps NSF Unidata stay on top of trends in Earth Systems Science education and research; for example, recent initiatives on Python and cloud-based computing have benefited tremendously from committee advice and involvement.

Version 5.2.2 of the netCDF Operators (NCO) has been released. NCO is an Open Source package that consists of a dozen standalone, command-line programs that take netCDF files as input, then operate (e.g., derive new data, average, print, hyperslab, manipulate metadata) and output the results to screen or files in text, binary, or netCDF formats.
