l3py - L3 Products in Python¶

What is l3py¶

l3py is a free Open Source software package for computing mass anomalies from time variable gravity field solutions. It is tailored for products of the GRACE mission and its successor GRACE-FO.

The features of l3py are:

• File I/O for common data formats including GFC files and COARDS compliant netCDF
• Basic arithmetic operations for sets of potential coefficients
• Propagation of spherical harmonic coefficients to gridded mass anomalies
• Spatial filtering of potential coefficients
