+  abstract: |
+    Micropaleomagnetic analysis offers a path to high-precision reconstructions
+    of ancient magnetic fields from terrestrial and space-returned samples by
+    inverting the vertical stray field of individual particles to recover their
+    magnetic moments through the use of magnetic microscopes. Constraining such
+    inversions requires a detailed understanding of how domain state influences
+    the dipolar and non-dipolar components of the stray field with distance.
+    Here, we use micromagnetic solutions of remanent states in real, irregular
+    sub- to near-micron magnetite particle morphologies to calculate vertical
+    stray fields at various heights, evaluating how dipolar and non-dipolar
+    signals can be recovered with both simple Cartesian dipole and multidipolar
+    models in the presence and absence of noise. Our results show that
+    single-domain and single-vortex state (SV) grains produce strong dipolar
+    anomalies that attenuate rapidly, limiting reliable detection to
+    observation heights below ∼1μm for 5nT noise or ∼0.5μm for 50nT noise.
+    Larger SV or multivortex grains remain detectable to ∼5-10μm but with
+    reduced moment fidelity. Multipolar components decay orders of magnitude
+    faster than the dipole and are quickly lost in noise at practical
+    distances. Dipole-only inversions yield stable, accurate results beyond
+    ∼2μm, while multipolar fits can improve near-surface accuracy but add
+    significant uncertainty in noisy data. Because strongly non-dipolar
+    anomalies observed at heights ≥1-2μm may arise from large multidomain
+    grains or from the combined response of short- and long-wave signals of
+    clusters of particles, they should be interpreted with caution. We
+    highlight the need to minimize sensor noise, optimize stand-off distance,
+    and carefully interpret signals for robust micropaleomagnetic measurement.
