We develop a method to estimate the power spectrum of a stochastic process on the sphere from data of limited geographical coverage. Our approach can be interpreted either as estimating the global power spectrum of a stationary process when only a portion of the data are available for analysis, or estimating the power spectrum from local data under the assumption that the data are locally stationary in a specified region. Restricting a global function to a spatial subdomain—whether by necessity… 
Spectral estimation on a sphere in geophysics and cosmology

TLDR
This work uses needlets (wavelets) on the sphere to construct natural and efficient spectral estimators for partially observed and beamed CMB with nonstationary noise and compares very favorably to the best pseudo-C{sub l} estimators, over the whole multipole range.

Slepian functions and their use in signal estimation and spectral analysis
TLDR
A theoretical overview of one particular approach to this "concentration" problem, as originally proposed for time series by Slepian and coworkers, in the 1960s, and how this framework leads to practical algorithms and statistically performant methods for the analysis of signals and their power spectra in one and two dimensions, and on the surface of a sphere.

Slepian Spatial-Spectral Concentration Problem on the Sphere: Analytical Formulation for Limited Colatitude–Longitude Spatial Region
TLDR
This paper exploits the expansion of spherical harmonics in the complex exponential basis to develop an analytical formulation for the Slepian concentration problem for a limited colatitude–longitude spatial region and designs a computationally efficient algorithm for the implementation of the proposed analytical formulation.
Revisiting Slepian concentration problem on the sphere for azimuthally non-symmetric regions
TLDR
The approach is different in a sense that the family of spatially concentrated bandlimited mutually orthogonal functions is obtained by maximizing the contribution of spherical harmonics components of all degrees and orders within the spectral bandwidth.

TLDR
It is shown that multitapering, or using sine or Slepian tapers, produces much better results than using the periodogram and is attractive compared with other competing methods when the technique is applied to a geophysical estimation problem.
