Geodetic mass balance of glaciers in the Manaslu region of Nepal 1970 - 2013

Dataset of the geodetic mass balance and surface elevation changes for the period 1970-2013 for glaciers in the Manaslu area of the Nepal Himalaya. Mean geodetic mass balances are computed from a 1970 DEM generated from CoronaKH4 imagery and 2013 HMA DEM elevations. Analysis was done at 8m spatial resolution.

Data formats:

Data are provided in two formats:

1) shapefile format showing the 1970 glacier outlines for 136 glaciers with valid coverage with a GLIMS ID and mean geodetic mass balance attributes, structured as follows:

[POINT_X]: Longitude of the glacier polygon centroid

[POINT_Y]: Latitude of the glacier polygon centroid

[GLIMSID]: ID of each polygon, generated from the lat long coordinates as per GLIMS standard guidelines

[src_image]: image source

[src_date]: date of the imagery

dh_ma-1: surface elevation change [meters per year]

bn_m_weq: geodetic mass balance [ m water equivalent per year]

err_dh_ma-1: error term for surface elevation change [meters per year]

err_bn : error term for the geodetic mass balance [meters water equivalent per year]

area_m2: area of each glacier polygon in m2

area_km2: area of each polygon in km2

line_type: types of glacier (clean/debris covered)

analysis_yr: year of analysis

2) excel file containing glacier GLIMS ID, mean elevation change and mean mass balance

Coordinate system: UTM datum WGS84 zone 45N
