Where can I get evapotranspiration data?

GloDET is a free portal to view and download global daily evapotranspiration (ET) spatial datasets. The data is calculated by the ALEXI two-source energy balance model, developed by the U.S. Department of Agriculture’s Agricultural Research Service.

What is MOD16?

A widely used algorithm to estimate ET at continental and global scale is MOD16 (MODIS Global Terrestrial Evapotranspiration Product). The algorithm was developed by Mu et al. [11] and Mu et al. [23] based on the Penman–Monteith equation, to monitor temporal and spatial variability of ET over global land surface areas.

What is evapotranspiration data?

Evapotranspiration is an estimate of the loss of water from both plants and the soil.

How do you calculate evapotranspiration?

Crop evapotranspiration is calculated by multiplying ETo by Kc, a coefficient expressing the difference in evapotranspiration between the cropped and reference grass surface.

What is the value of MOD 16?

To find 1 mod 16 using the Modulo Method, we first divide the Dividend (1) by the Divisor (16). Second, we multiply the Whole part of the Quotient in the previous step by the Divisor (16). Thus, the answer to “What is 1 mod 16?” is 1.

How do you calculate modulo?

How to calculate the modulo – an example

1. Start by choosing the initial number (before performing the modulo operation).
2. Choose the divisor.
3. Divide one number by the other, rounding down: 250 / 24 = 10 .
4. Multiply the divisor by the quotient.
5. Subtract this number from your initial number (dividend).

Which is version 6 of MODIS evapotranspiration data?

The Version 6 products are a continuation of this project. Validation at stage 3 has been achieved for the MODIS Evapotranspiration data products. Further details regarding MODIS land product validation for the MOD16 data products are available from the MODIS Land Team Validation site.

What can mod16 global evapotranspiration be used for?

MOD16 global evapotranspiration product can be used to calculate regional water and energy balance, soil water status; hence, it provides key information for water resource management.

What can mod16 et algorithm be used for?

The MOD16 ET algorithm has a good performance in generating global ET data products, providing critical information on global terrestrial water and energy cycles and environmental changes (Mu et al., 2007a, 2009, 2011).

What are the different types of mod16 products?

MOD16 products includes 8-day, monthly and annual ET, LE, PET, PLE and 8-day, annual quality control (ET_QC). The 8-day MOD16A2 QC field is inherited from MOD15A2 in the same period.
