**Description of the desired feature** Airborne gravity data usually involves correcting for non-gravitational accelerations. It would be great to have these implemented in Harmonica since they are hard to find...

**Description of the desired feature** We know that fitting an EQL gridder is a process that requires a fair amount of memory, mainly to store the Jacobian matrix. One small...

enhancement

**Description of the desired feature** Would be nice to have an equivalent layer gridder that works in geodetic coordinates. This means that the data points and the location of the...

**Description of the desired feature** Just came across the paper [Potential field continuation in spatial domain: A new kernel function and its numerical scheme](https://doi.org/10.1016/j.cageo.2020.104405) by Zhikui Guo (@zguoch) and Chunhui...

**Description of the desired feature** Our forward modelling code (`harmonica/forward/`) uses numba to speed up computations. It can be a bit picky about input data types and doesn't like it...

enhancement

We have [an example of global gravity disturbance](https://www.fatiando.org/harmonica/dev/gallery/gravity_disturbance.html#sphx-glr-gallery-gravity-disturbance-py) calculation using spherical harmonic data. This is a global grid and is straight forward to calculate the geometric heights using gridded geoid...

**Description of the desired feature** Would be nice to implement the fast iterative equivalent layer technique described on [Siqueira, Oliveira Jr. and Barbosa (2017)](https://www.pinga-lab.org/papers/paper-fast-iterative-eqlayer-grav-2017.html). It could be a fast alternative...

**Description of the desired feature** PRs #17 and #36 added a function to calculate the Moho depth based on an Airy isostasy model. It would be great to have a...

good first issue

Hi, I was wondering if this might be an interesting feature, as harmonica also offers Airy isostatic calculation which is a special case of the flexural rigidity calculation. Actually, GMT...

enhancement

During my bachelor thesis I worked on gravity forward modelling using prisms. Since I focused on a terrain correction, the datasets used are very massive and caused long computation times....
