Summary
Abstract:
Soil Moisture for Western Russia and the Ukraine is historical digital data set DSI-6411, archived at the National Climatic Data Center (NCDC). Historical data set DSI-6411 is comprised of soil moisture data and the accompanying information for the agricultural regions of Western Russia (European Russia, west of the Ural Mountains) and the Ukraine for late 1991 ... through 1996. This data is collected routinely for agro-meteorological monitoring of these two
nations and serves as an input for the in-situ assessment of the state of the major crops. Plant
available soil moisture in the upper first meter (for several layers) is a key element of this
monitoring, and is collected in the near-real time with a 10-day time step. This information
cannot be assessed properly without extensive metadata that characterize the soil type and agro
physical properties of the upper first meter of the soil at each field. These metadata are
defined once per 10-15 years, are rarely reassessed and thus named soil constants. Soil moisture
measurements are made during the warm period of the year. In the cold season, an essential part
of the agro-meteorological monitoring is the information about snow depth at the agricultural
fields. This information (only for Russia) is also included in this data set. Agro-
meteorological stations of the former Soviet Union have an elaborate observational program that
fits the needs of crop monitoring. Soil moisture content is measured by gravimetric methods
during the warm season, specific for each crop. The results of this monitoring are prepared 3
times per month (on the 8th, 18th, 28th of each month). The regular observations are made from
the beginning of the field work (as a rule in April) until harvest time. An English-language
detailed description of the gravimetric method can be found in Vinnikov and Eserkepova (1991)
and Robock et al. (1995). These measurements are made at depths of 0-5 cm, 0-10 cm, 0-20 cm,
0-50 cm, 0-100 cm (0-10 cm, 0-20 cm, and 0-50 cm for potatoes). In The Ukraine, measurements for
two layers (0-20 cm and 0-100 cm) are made most regularly. These undergo a laborious manual
quality control and are used in regionally averaged characteristics of the state of the crops.
If a station is used for monitoring a given crop, each soil moisture measurement is an average
of measurements at four points of the same agricultural field with this crop. Soil type, field
capacity, volumetric density, and wilting level are periodically evaluated (or on file) for most
of these fields. All Ukrainian stations and approximately 70% of Russian agro- meteorological
stations, have these hydrological constants on file. Snow depth and density is monitored through
the agro-meteorological network. This information is also included as accompanying information
to the data set. While the gravimetric method allows us to measure total water content of the
soil level, the agronomists are actually interested in plant available soil moisture. Therefore,
for each field a soil constant non-productive soil moisture is subtracted from soil moisture
measurements and the data of agro-monitoring are provided in the units of the plant available
soil moisture. The non-productive soil moisture at each field is defined as soil moisture at the
wilting level and is included or can be derived from the soil constants available in this data
set. ********************************************************************** Table 1. Data on

Period of observations: April-July Crop: Winter wheat Number of stations: 71 Period of
observations: Spring-Summer-Fall Note: In 1992, the Ukrainian meteorological service
discontinued the fall observations of soil moisture for winter wheat at the layer 0-100 cm. The
period of crop soil moisture observations depends on the weather situation during the vegetation
season (initial spring conditions and the speed of plant development). It may differ
significantly (from start and finish) from year to year. As usual, in autumn, the winter wheat
soil moisture observations continue in the new field at the same station. The timetable of the
soil moisture observations in Russia and the Ukraine is given in Table 3.
********************************************************************** Table 3. The timetable of
the soil moisture observations. Season: Autumn Winter WHEAT: after havesting the preceding crop
until late autumn OTHER CROPS: No Season: Spring and Summer Winter Wheat: after renewals of
vegetation until max maturity Other Crops: after start of spring works until max maturity The
format of the records in the soil moisture data set was specially designed to fit into any
database. Russian and Ukrainian data sets have different formats. The Ukrainian data major
parameters are crop type, station name and id, depth of soil layer in soil moisture measurement,
date of observation, and estimated soil moisture value. The Russian data major parameters are
crop type, station id, plants condition code, quanitity of weeds code, plants height at last
day, plants density, average weight of plant (maize only), and soil water content in the
following soil layers: 0 to 1 m, 0 to 50 cm, 0 to 20 cm, 0 to 10 cm, and 0 to 5 cm.

(See missing data to see which data were deleted) b) Between 23:30 Jan 13 and 00:30 Jan 14, and
between 16:30 Jan 18 and 0100 Jan 19 there were erratic high positive and high negative
turbidity readings. Also on Jan 27 03:30 turbidity was low. It is unclear if these data are
obstructions, probe malfunctions, or out of water (OOW) events. See missing data to see which
data were deleted. c) The following data are suspect due to low conductivity readings and
negative depth; Jan 17 21:30-01:30 Jan 18 Jan 18 20:30-01:30 Jan 19 Jan 19 16:30-02:00 Jan 20

17:30-02:30 Feb 21 Feb 21 19:30-03:30 Feb 22 Feb 22 17:30-04:30 Feb 23 South Marsh a) There were
lots of negative turbidity data during the month of February and the probe seems to have
experienced the same type of malfunction. Symptoms are extremely high values followed by a
negative value, which is always 0.7. Post deployment DI reading was 30. At 10:30 on
Feb 2 the first 0.7 was recorded. Turbidity data was deleted beginning 03:00 Feb 4 to
the end of the month due to probe malfunction. b) Beginning 20:30 Feb 12 to 23:30 Feb 28 DO% and
DO mg/L are suspect due to probe malfunction. Data was deleted. March 1-30, 1998 Sampling Period

PROCESS DESCRIPTION: Additional Description: Entry verification The Centralized Data Management
Office re-processed all SWMP water data collected from 1995-2002 to include an identifying
station code (three letter reserve code, two letter sampling site code and data type code), a
four digit year date stamp (mm/dd/yyyy) and a corrected time column (hh:mm). With the new
format, the use of periods to denote deleted or missing data has been abandoned. Hence, all
periods contained in the SWMP water data collected prior 2003 were removed and left blank. :
Data are uploaded to the PC from the YSI and graphs are produced and examined using the PC 6000
software. Data are also uploaded in a comma-delimited format from the YSI to the PC. Edited
files are created by removing headers, footers, and spaces on a PC in Excel 5.0. Suspect data
are evaluated using QA/QC macros (version 3.0) from CDMO. Missing data from YSI maintenance are
inserted into the spreadsheet and are denoted by periods (.). Edited files are merged to create
one full month of data. Edited and raw data are archived at Elkhorn Slough NERR. John Haskins is
responsible for the editing and archiving of data. PROCESS DATE: 20060209
