We are pleased to announce the release of IRIS DMC’s Noise Toolkit (NTK) data product v2. The NTK is a collection of Python 3 programs to assist users with 1) computing Power Spectral Density (PSD) of station waveform data using customized parameters, 2) computing microseism energy from PSDs at different frequency bands and 3) with performing frequency-dependent polarization analysis of waveform data.

Highlights of the major changes included in this release are:
• A significant change in how data are requested. With the v1 release, only data from IRIS or user local disk were retrieved, but v2 supports data retrieval from all FDSN data providers via our FedCatalog service (http://service.iris.edu/irisws/fedcatalog/1/). See https://ds.iris.edu/gmap/ for a map of the FDSN stations from different data centers
• The PDF/PSD package now uses matplotlib.csd to compute PSDs
• All three packages have been upgraded to Python 3
• All programs have been updated to follow PEP 8 as much as possible, although some of the old-style code still remains for compatibility
