Mars Watershed boundary data for "Global Spatial Distribution of Hack's Law Exponent on Mars Consistent with Early Arid Climate "

This is the watershed boundary data for Mars (along with Hack's Law exponent) as described in Luo et al. "Global Spatial Distribution of Hack’s Law Exponent on Mars Consistent with Early Arid Climate" accepted for publication in Geophysical Research Letters on 3/10/2023.

The attributes are as follows:

Id, gridcode = ID of basin

Shape_Length = perimeter of the basin

Shape_area = area of the basin

geoArea = geodesic area of the basin

geoLength = geodesic perimeter of the basin

areaR = geoArea / Shape_area

LengthR = geoLength / Shape_Length

n_exponent = Hack’s Law Exponent (h in L = k A^h)

n_coefficient = Hack’s Law exponent  (k in L = k A^h)

n_r2 = r^2 of the nonlinear fit (optimize.curve_fit function in SciPy)
