Snow to Ice Thickness Conversion Calculator

Conserve measured layered snow mass when compacting to supplied ice density, distinct from water equivalent; air/water inclusions and densification timing are not inferred.

Description

Compaction from snow to a selected ice density can conserve layer mass.

Compaction from snow to a selected ice density can conserve layer mass. Ice-equivalent thickness differs from water-equivalent thickness.^[1]

Enter aligned nonempty nonnegative layer depths/positive densities and positive target density with every snow density≤target. Return layer equivalents and total.

When to use Snow to Ice Thickness Conversion Calculator

Use Snow to Ice Thickness Conversion Calculator when you need to evaluate the supplied records under the calculation and evidence rules below. No densification timing, air/water inclusions or density estimation is inferred.

Prepare the observed ice, snow, water or geometry measurements and explicit calibration parameters requested. Keep coordinates, datum, density and time units consistent.

How to use Snow to Ice Thickness Conversion Calculator and understand its results

Prepare the observed ice, snow, water or geometry measurements and explicit calibration parameters requested. Keep coordinates, datum, density and time units consistent.
Enter snowLayerDepthsM, snowLayerDensitiesKgM3, targetIceDensityKgM3 using the field table and calculation rules, then run the tool.
Read layerIceEquivalentThicknessesM, totalIceEquivalentThicknessM. The explanation below defines the units, signs, ordering and any flags or placeholder values.
If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.

Input field	Meaning	Value type; see rules below	Requirement
snowLayerDepthsM	Snow layer depths m	list of number	Required
snowLayerDensitiesKgM3	Snow layer densities kg m3	list of number	Required
targetIceDensityKgM3	Target ice density kg m3	number	Required

Enter aligned nonempty nonnegative layer depths/positive densities and positive target density with every snow density≤target. Return layer equivalents and total.

iceThickness[i]=snowDepth[i]×snowDensity[i]/targetDensity

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
layerIceEquivalentThicknessesM	Layer ice equivalent thicknesses m	list of number
totalIceEquivalentThicknessM	Total ice equivalent thickness m	number

Limitations and assumptions

No densification timing, air/water inclusions or density estimation is inferred.

Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Numeric lists are limited to 10,000 entries; string lists to 128 strings of at most 128 characters each. The rules above may impose smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.

Alternative or Complementary methods

Use Water Equivalent Snow Depth Calculator: Snow water equivalent expresses a measured snow-core mass as a water depth. Core area and tare correction determine its measurement basis. For a complementary task, use Close Off Age Lock In Depth Calculator: Layer mass and steady accumulation can estimate ice residence age at supplied firn depths. Ice age differs from trapped-gas age.
