VanderSat Data Products¶
This chapter describes the VanderSat data products. This a technical description. Background documentation including scientific papers describing the algorithm can be obtained on request. Information can also be found here: FAQ.
Product Data Flags¶
Most VanderSat products have an associated file with a quality indicator or data flag. These are stored as separate products in our system. See How to retrieve the data flags and Flags data file description for LST, VOD and SM for information on how to retrieve and interpretate the flags.
Product naming convention¶
VanderSat data products follow a simple three-part naming convention:
{product-name}_{version string}_{resolution}.
| product-name: | The name of the product. This name itself usually consists of
several parts separated by hyphens (-). The first part is the
actual product (eg.e SM, ‘TEFF etc), the other (usually
three ) parts give the product attributes, e.g.:
SM-{SAT}-{BAND}-{TIME}. Here {SAT} will be replaced by
the satellite/instrument {BAND} will be replaced by the
frequency band the product has been derived from, {TIME}
will be replaced by the part of the orbit (ASC or DESC).
For example SM-SMAP-LN-DESC specifies soil moisture for the
SMAP satellite using L band without vegetation correction (see
Vegetation correction) derived from the descending orbit
and QF-AMSR2-SM-C1V-DESC specifies the quality flags for
soil moisture derived from the AMSR2 instrument descending
C-band with vegetation correction. |
|---|---|
| version string: | The version string is made up of 4 positions. Is always starts with a V and the remaining three positions denote a integer number padded with zeros (e.g. V001 or V034 are describing version 1 and version 34 respectively). Minor version information can be found in the meta data of the actual data products. |
| pixel size: | pixel size is given as a number in metres. This is an approximate size as the data itself is stored in decimal degrees (WGS84). The actual size in decimal degrees is given in the description of each data product. |
Vegetation correction¶
In certain cases a vegetation correction is applied to the soil moisture (SM)
and vegetation optical depth (VOD) products. This is denoted in the product
name such that SM-C1N is the normal product and SM-C1V is the
vegetation corrected version of the product. In the majority of cases, the
normal product will be used. If the vegetation corrected product is required we
will let you know.
Volumetric Soil Moisture L-band (SM)¶
Description¶
Satellite observed volumetric soil moisture derived from L-band microwave data in combination with other bands. It is based on VanderSat’s patented high resolution technology and provides soil moisture of the top 5 cm of the soil depending on moisture conditions.

Derived Root Zone Soil Moisture (DRZSM)¶
Derived Root Zone Soil Moisture is calculated from one of the direct soil
moisture products (Volumetric Soil Moisture L-band (SM), Volumetric Soil Moisture C-band (SM), Volumetric Soil Moisture X-band (SM)) using a
method described by Albergel et al., 2008.
(https://doi.org/10.5194/hess-12-1323-2008) and Paulik et. al. 2014,
https://www.sciencedirect.com/science/article/pii/S0303243414000099). The
characteristic time T is part of the product name. In case of single point
timeseries retrieved via the API this can be calculated directly on the fly
using the API (see timeseries-api). For gridded data the maps have been
pre-calculated using a number of pre-defined T values. The DRZSM is also
calculate for periods with missing input data. If data is missing the will be
reflected in the quality flag that is stored in a separate file (see
DRZSM quality indicator).

| Versions | Version 0.9: Noordwijk, Version 1.0: Haarlem, Version 3.0: Champaign |
| Unit | \(m^3/m^3\) |
| T value | 10, 20 |
| Pixel size | 100x100m, 0.000888888888889 degree |
| Temporal resolution | 365 images/yr |
| Coverage | Global |
| Data availability | April 2002 - Present; gap in 2012 |
| Satellites used | AMSR-E, AMSR-2, SMAP |
| Available to user | 12 hours after overpass of the satellites |
| File format | GeoTIFF, NetCDF (Images), csv (Time series) |
| Data delivery | VanderSat API, VanderSat Viewer |
The name of the DRZSM also includes the top soil soil moisture it is derived
from and the T value used in the creation of the DRZSM. For example
DRZSM-AMSR2-C1N-DESC-T10_V003_100 contains root zone soil moisture derived
from C-band data using a T value of 10. Alternatively
DRZSM-SMAP-LN-DESC-T20_V003_100 contains root zone soil moisture derived
from L-band data using a T value of 20.
